You’ve probably seen the posters. Bud Abbott and Lou Costello looking terrified, surrounded by shadows and a suspiciously dead body. It was 1942. The world was at war, and Universal Pictures needed a hit that wasn't just another monster movie. They found it in Who Done It 1942, a film that basically invented the blueprint for the modern horror-comedy mashup. Honestly, it’s a bit of a miracle the movie even exists in the form we know today.
Back then, Abbott and Costello were the biggest thing in Hollywood. Like, untouchable. They had just finished Ride 'Em Cowboy and Pardon My Sarong, and audiences were hungry for their specific brand of fast-talking, slapstick chaos. But Who Done It 1942 did something different. It took the tropes of the "Old Dark House" mystery—the kind of stuff Agatha Christie or Mary Roberts Rinehart would write—and smashed it into a radio station setting. It was meta before people even used the word meta.
The Chaos Behind Who Done It 1942
The plot is deceptively simple. Chick Larking (Bud) and Mervyn Q. Milgrim (Lou) are soda jerks working at a radio station. They want to be mystery writers. When a real murder happens during a broadcast, they decide to "investigate" to get material for their big break. It sounds like a standard sitcom setup, but the execution in Who Done It 1942 is surprisingly tight.
Director Erle C. Kenton didn't just let the boys ad-lib everything. Kenton was a veteran. He had directed Island of Lost Souls (1932) and would go on to do House of Frankenstein. He knew how to light a scene to make it actually look creepy. That’s the secret sauce here. If the mystery felt fake, the jokes wouldn't land. If the jokes were too broad, the mystery would lose its stakes.
There's this specific scene involving a recording device. It’s one of the best examples of their "wordplay" humor transitioning into physical comedy. Lou is trying to follow instructions, Bud is yelling, and the tension of the looming murder investigation keeps the pacing frantic. It’s short. It’s punchy. It works because the stakes are real.
Why the Radio Setting Mattered
Radio was the internet of 1942. It was how everyone got their news and their laughs. By setting Who Done It 1942 in a bustling broadcast center, Universal tapped into a very specific cultural anxiety of the time: the idea that the voice you hear in your living room might not be who you think it is.

The supporting cast is also stacked. You’ve got William Gargan and William Bendix playing the "real" detectives who are constantly two steps behind our heroes. Patric Knowles and Louise Allbritton provide the "straight" roles that ground the movie. Honestly, Bendix steals almost every scene he’s in just by being incredibly frustrated. It’s a masterclass in the "slow burn" reaction.
The film was shot quickly. Production started in late August of '42 and it was in theaters by November. That’s a turnaround time that would give modern producers a heart attack. But that speed gives the film an energy. It feels breathless. It feels like everyone involved was having a blast, even if they were working 14-hour days on the Universal lot.
Dissecting the Mystery Tropes
People often forget that the 1940s were obsessed with the "whodunnit." Who Done It 1942 leans hard into the clichés.
- The victim is a wealthy network executive (Colonel J.R. Coleman).
- The murder method is bizarre (electrocution via a rigged microphone).
- The suspects all have motives ranging from debt to professional jealousy.
But the movie subverts these by making the "detectives" the least competent people in the building. It’s a parody of the Thin Man series or the Perry Mason radio plays. When Chick and Mervyn try to recreate the crime, they almost kill themselves multiple times. It’s funny, sure, but it also highlights how ridiculous the "genius detective" trope had become by 1942.
One of the most famous sequences is the rooftop chase. It’s classic Abbott and Costello. Lou is dangling off the side of the building, the killer is closing in, and Bud is trying to save him while also trying to solve the puzzle. The stunt work here—largely done by doubles but featuring some genuine precariousness from Lou—is genuinely impressive for the era. No CGI. Just a guy on a wire against a painted backdrop of the Los Angeles skyline.

The Impact on the Genre
Before Who Done It 1942, comedy and mystery were usually separate entities. You had "scary" comedies like The Ghost Breakers (1940), but they leaned more into the supernatural. This was a "fair play" mystery. You could actually follow the clues if you paid enough attention between the jokes.
It paved the way for Abbott and Costello Meet Frankenstein later in the decade. It proved that you could put these two into a high-stakes, life-or-death situation and the audience would still laugh. They weren't just clowns anymore; they were characters navigating a dangerous world.
Critics at the time were surprisingly kind. The New York Times noted that while the plot was "as thin as a radio script," the duo's energy carried it. That's the thing about this movie—it doesn't try to be Citizen Kane. It tries to be a distraction. In 1942, with the war looming over every household, a distraction was exactly what the doctor ordered.
Real Facts Every Fan Should Know
There are some weird bits of trivia that make Who Done It 1942 even more interesting to watch today.
- The Musical Numbers: Unlike many other Abbott and Costello films, this one is relatively light on the singing. Usually, you'd have the Andrews Sisters or some big band act stop the movie for ten minutes. Here, the musical interludes are shorter, keeping the focus on the murder plot.
- The "Volts" Joke: There's a running gag about "volts" and "watts" that is a direct descendant of their "Who's on First?" routine. It’s fast, rhythmic, and requires insane timing.
- The Budget: Despite being a "B-picture," it looks expensive. Universal used their existing sets to make the radio station look cavernous and modern.
- The Ending: No spoilers, but the way the killer is revealed is actually pretty clever for a comedy. It uses the technology of the time (radio recording) as a plot device.
The film also captures a moment in time before Lou Costello’s health started to decline. He’s incredibly physical here. Running, jumping, falling—he’s like a rubber ball. His chemistry with Bud Abbott is at its absolute peak. They don't even need to look at each other to know when to swap lines. It’s telepathic.

Why You Should Watch It Today
Honestly, Who Done It 1942 holds up better than a lot of its contemporaries. The jokes about fame and the "magic" of radio feel oddly relevant in the age of podcasts and influencers. Everyone in the movie is trying to "make it." Everyone has a side hustle.
The mystery is solid enough to keep you guessing, but the real draw is watching two masters of their craft at the height of their powers. If you’ve only ever seen clips of them, this is the movie to watch in full. It’s the perfect entry point.
If you’re looking to dive into the world of Who Done It 1942, here is how to get the most out of it:
- Watch for the Background Actors: Universal used many of the same character actors in their horror films. You’ll see faces that look familiar if you’re a fan of the Wolf Man or Dracula sequels.
- Listen to the Sound Design: For a 1942 film, the use of "on-air" vs "off-air" sound is really sophisticated. It helps define the spaces of the radio station.
- Focus on the Pacing: Notice how the comedy bits always happen during a moment of plot progression. There’s very little "filler" in this 75-minute runtime.
To truly appreciate the film, compare it to the radio mysteries of the same era, like The Shadow or Inner Sanctum. You'll see exactly what they were parodizing. The movie is a love letter to a medium that was changing the world, wrapped in a silly, wonderful, slightly spooky package.
Next Steps for Classic Film Fans
To get the full experience of 1940s comedy-mysteries, your next step should be a double feature. Pair Who Done It 1942 with Bob Hope’s The Cat and the Canary. It’ll give you a perfect sense of how different studios handled the "scary comedy" balance. After that, look for the original radio broadcasts of The Abbott and Costello Show from 1942 to see how they adapted their stage presence for the mic—it's the exact world they were spoofing in the movie. Don't just watch the film; look at the context of the era to see why it was such a massive hit.
