Why Him? wasn't one of the best comedies of the last decade by any stretch (the film is "solidly cast but overall misconceived," according to Rotten Tomatoes), but it did produce one particularly hilarious blooper. The film revolves around a dad's (Bryan Cranston) efforts to stop his daughter's super rich, tech-bro boyfriend (James Franco) from proposing. Cranston and Franco's back-and-forth does bring on the odd chuckle, but the Breaking Bad star's funniest interaction is with Franco's friend/trainer/PA Gustav, played by Keegan-Michael Key.
In one scene, Cranston gets stuck in Franco's bathroom when the millionaire's fancy, paperless toilet malfunctions. The only way he can get cleaned up is if the system is manually rebooted, and that's where Key comes in. "Keegan was't actually supposed to come into the room in that scene, but the night before, I rewrote the scene because I was like, 'I have Keegan, and I have Bryan on the toilet, I think he should come into that bathroom,'" director John Hamburg said. It was a small scene, but it took a very long time to film because Cranston just couldn't stop laughing at the ridiculousness of the situation. "I would just kind of move into frame, really, really slowly, as close as I could next to his face," Key recalled. "Every single time he would break. ... He must have apologized 56 times. ... You can palpably see the frustration."
