Swampflix readers, the internet has been essentially de-democratized. What I mean by that is that when you or I go online to look for the answer to a question or read one (1) article about a thing that we engaged with or enjoyed, we no longer get to interact with that article in a vacuum. Unless you’re VPN’d up every single time that you look for a movie review or try to purchase a replacement ice mold for the Rival snow cone maker that you purchased at an estate sale without realizing that it required a part that was not present, you’re going to start getting ads for snowball machines and your YouTube homepage is going to be flooded with think pieces and video essays about the film that you just wanted one critic’s viewpoint on. Well, that and advertisements and algorithmically driven content to make you stay on the platform longer, feel encouraged to interact with the content to drive engagement, etc. Like most Swampflix contributors, my interests are not fully in alignment with the zeitgeist, but every once in a while, they are; unfortunately, although that means that I was as excited about M3GAN as the culture at large was, discussion of her wasn’t omnipresent in the discourse of the YouTube channels that I haven’t blocked. But boy howdy did YouTube love that I loved Glass Onion. Amidst a deluge of clickbait bids titled “[Number] Things You Missed in Glass Onion!”, “All the Secret Connections between Knives Out and Glass Onion!”, and the like, I have to admit that I did encourage the algorithm just a little by watching videos that talked about the various films and TV shows that had served as inspiration for the film, because I go through periods where mysteries are all that I ever want to consume. Frequently cited as a major creative jumping-off point for the film was 1973’s The Last of Sheila. 

Helmed by director Herbert Ross and scripted by Anthony Perkins and Stephen Sondheim (the only screenplay credit for each), the film tells the story of film producer Clinton Greene (James Coburn) and his plan to take several of his friends on a pleasure cruise aboard his private yacht. Their voyage begins, presumably not accidentally, on the anniversary of the death of Greene’s girlfriend, Sheila, who left one of his parties in a fit and was killed by a hit-and-run driver mere blocks from his house. An avid player of games of strategy and wit, Greene has planned out a series of mystery nights where his guests will go ashore with a set of clues and split up to try and solve a mystery. Each person aboard is also given a card that is to be their “secret identity” for the game, and the first of these that we see as characters open their envelopes are things like “Alcoholic,” “Shoplifter,” and “Homosexual.” Further, each of his traveling companions was there the night of Sheila’s death: Christine (Dyan Cannon), a film talent agent who’s full of wit and flirtatiousness in that a 1970s showbiz liberated way; glamorous but troubled starlet Alice (Raquel Welch) and her current beau, another film agent named Anthony (Ian McShane), who’s forever angling to get more involved with the production side of film; faded movie star and giant of another age Philip Dexter (James Mason) who’s now stuck in undignified commercials for dog food; and Tom Parkman (Richard Benjamin), a screenwriter who’s been stuck doing rewrites on spaghetti westerns while his original work remains unsold and unproduced. The only person on the cruise whom we are explicitly told wasn’t there the night Sheila died isTom’s wife Lee (Joan Hackett), a kind but idle and neurotic heiress. The first night of the mystery game is largely a success, with half of the group getting to the secret while the other half is either too late or doesn’t try at all. On the second night, however, tragedy strikes, and when not everyone comes back to the boat, our cast of characters return to the site of the previous evening’s game and discover that someone from their number has died, under mysterious circumstances. 

Excited as I was to finally see this film, at a full two hours, it starts to feel its length in places. The site of the second night’s game is an abandoned monastery where the gang has to don identity-revealing robes and remain quiet until they locate the confessional in which Greene is hiding, which makes for a lot of fun as characters pass each other without we in the audience ever really knowing with whom they’re speaking or even if the characters know; unfortunately, this runabout through the monastery feels much longer than the ten minutes of screen time that it occupies and unfortunately telegraphs that a twist is coming. For the first hour of the movie, the omnipresent implication is that Greene has arranged some elaborate plan to discover which of his guests was Sheila’s killer, but a savvy viewer will know that there’s simply no time left in the runtime of the film to go through five more puzzles, and so there’s going to be a complicating factor at any moment. You’re not surprised by the second death, merely by who is the unfortunate corpse. I’ll be the first to admit that I might have been spoiled (or had a certain part of my brain atrophy while another part grew three sizes) by watching some 250+ episodes of Murder, She Wrote in the past thirteen months, so I could be stuck on that formula, but an hour in feels like an awfully late place to stick your midpoint murder twist. At the same time, there’s no fat to trim here, no extraneous beats that don’t reveal something relevant about character, motive, time, and secrecy, it’s just that the relevancy of all of these narrative moments is often revealed late in the game. 

If there are two performers who stand out to me, I’d have to name Cannon and Hackett. Every performance here is good, but Cannon is delivering a wonderfully understated performance as a woman who’s committed to living life as sensually and hedonistically as possible but whose dark past she regrets; she’s stunning. A whodunit like this doesn’t require the sincerity and humanity that she brings to her delivery of a monologue in which she confesses to having furthered her career by slipping some names to the HUAC, but it certainly elevates it. “Then those people didn’t work for a while,” she says. “Now they work. Sometimes I try and get them work. Sometimes I see them on the street and sometimes … they cross the street.” She tries to play off her guilt, but no one is convinced, least of all herself, and it’s magical. Also doing great work here is Hackett, whose frantic, nervous, chain-smoking Lee is clearly having a very hard time with all of this business right from the start as the only person aboard who doesn’t belong there, since she was hundreds of miles away when Sheila died. As the only person we can be assured isn’t a killer, she seems to understand the jeopardy of being on the boat with someone willing to cover up their hand in an accident that resulted in a death. After all, someone almost kills Christine by turning on the yacht’s propellers while she’s taking a swim; who’s to say there won’t be more “accidents”? The big stars are clearly supposed to be Mason and Benjamin, the actor and the writer, who take point on trying to spin out the narrative that would lead to the things that the group has uncovered and discovered—and let there be no mistake, they are both more than satisfactory, with Mason having the upper hand over Benjamin in the charm department—but it’s Cannon and Hackett that I’ll be thinking about weeks from now. 

Let’s talk humor. I’d be remiss if I didn’t mention that, alongside the performances, the other tempering element that helps the movie feel like it’s got some pep in its step when it gets a little slow is the film’s comedic wit. Before she can even get on the boat, Christine complains about the lack of a drink in her hand by declaring “My mouth is so dry they could shoot Lawrence of Arabia in it,” which I’ve found myself saying every once in a while over the years without ever remembering its origin (it’s the pull quote used for the film in Douglas Brode’s compendium—and my longtime companion—Edge of Your Seat: The 100 Greatest Movie Thrillers, where it ranks at 88th). Even the jokes that characters make that are supposed to be either unfunny or in bad taste within the text got a chuckle out of me, especially those that poke fun at Hollywood and celebrity culture. This includes Greene’s mocking of Tom’s body of work as a second set of eyes on Westerns by asking him to read from a section of Fistful of Lasagna (“or whatever it’s called”). Even if the references are a half century old now, the core truths in play keep the film feeling fresh, despite some major dissonance in other areas that it’s important to address: one of the characters is outed as a child molestor, which is bad enough, but the other characters don’t really seem to think that it’s a problem that needs to be addressed or even has a glimmer of an idea of reporting him to the authorities. If there’s one thing in this film that hasn’t aged well, it’s the casualness with which that horrifying little tidbit is dropped and the lack of reaction to it. 

Already, I’ve risked giving away too much of the plot of this one, so I’ll wrap it up. Stellar performances, creative misdirects and clues, and clever jokes stashed away in little corners more than make up for the times where the film feels like it’s dragging the bottom. Although you can rent this one streaming, I’m sure your local library has a DVD that’s probably got some fun extras and easter eggs on it, so why not visit them instead?
