The Man with Two Brains does not age well. It’s a case study in not aging well, even more so because when the three writers—director Reiner, star Steve Martin, and George Gipe—can’t figure out how to do an ending so they just do an extended fat joke… well, it’s hard to continuing giving the film a pass. Not after a racial epithets joke, which the film doesn’t even realize is lazy.
Because it does recognize its easy jokes. There are a lot of easy, easy, easy jokes Brains wants to get away with and it usually is able to do it thanks to Martin or co-star Kathleen Turner, but the finale doesn’t use anyone well. In fact, it’s a call back to a completely different section of the film they probably don’t want to be recalling.
The movie’s got a really peculiar structure. The first act is about Martin falling for evil gold digger Turner (not knowing she’s an evil gold digger) and her refusing to consummate the relationship. So boss Peter Hobbs (who’s pleasantly sturdy and game for even the fail jokes) sends Martin off to Europe for a conference; a little continental seduction and so on.
In Europe, Martin meets mad scientist David Warner, who’s—oh, right. Martin’s the world’s premier brain surgeon. Anyway. He meets Warner, who’s a mad scientist who wants to transplant brains he’s been keeping alive thanks to hydroxychloroquine or something. Warner’s oddly disappointing in the film. I was expecting something from him and he never does anything. The film’s got problems with the supporting characters though; Warner’s butler, Paul Benedict, gets more personality than Warner in fewer scenes with less exposition. Reiner’s direction is… not great. He and Martin (and Gipe) are trying a lot of different things, some things are a lot less successful than others.
And even the big successes are often qualified. Like when Martin is prowling the streets to find a woman to murder so his soul mate—a disembodied brain voiced by Sissy Spacek—can find a new home. It’s all very complicated, with the brain stuff being Martin finally getting free of animate costars and getting to do his wild and crazy guy thing in the spotlight. It’s better when he does it opposite other cast, specifically Turner, who frequently can’t hold her femme fatale. Martin so funny she’s laughing. It’s brings Turner almost too much personality.
Back to that successful sequence—Martin lurking the streets of Vienna, looking for a woman to murder. All of a sudden the backlot shooting starts to work—Reiner and cinematographer Michael Chapman(!) shoot Two Brains like they’re trying to figure out how to not make it look like a sitcom but end up making it look more like one because of how they compensate. Like Joel Goldsmith’s ludicrously inappropriate synth score; it ups the zany so you don’t think too much about Martin’s premeditated murder scene and so on, but it’s also terrible. And doesn’t help the scene. Ever. In fact, it’s always actively hurting it.
Overall, Two Brains doesn’t have the pieces to succeed. The story’s not there. The plotting isn’t there. The pacing’s there. The direction’s not there. Martin and Turner do an excellent job doing absurd caricatures (at best, Martin does just mug occasionally), but it’s like no one’s curating the gags or even taking note of their successes. It’s got its ambitions just no idea when they realize.
