According to multiple actors, Steven Seagal is an incredibly difficult coworker, something John Leguizamo discovered the hard way. While filming Executive Decision, Seagal got angry with his costar and allegedly shoved Leguizamo against a wall. Maybe he'd just watched Super Mario Brothers?

Seagal also made life hard for the Saturday Night Live cast. While hosting the show in 1991, he was "very critical of the cast and writing staff." According to Tim Meadows, Seagal "didn't realize that you can't tell somebody they're stupid on Wednesday and expect them to continue writing for you on Saturday." David Spade, meanwhile, said that in his six years on the show, Seagal was the absolute worst host, which probably had a lot to do with the aikido king's taste in comedy. According to Julia Sweeney, Seagal wanted to perform a sketch where he played a therapist who wants to sleep with a rape survivor. Ha ha? Evidently, Seagal was so frustrating, he was banned from ever hosting again.

Stephen Tobolowsky also learned firsthand about Seagal's petulant ways. In The Glimmer Man, Tobolowsky played a serial killer — naturally, Seagal was supposed to blow the bad guy away. But then Seagal decided it was "bad for his karma" to keep killing people onscreen. Now, he wanted Tobolowsky to survive. Thinking on his feet, Tobolowsky explained that his character was trapped in his own private Hell. By killing the villain, Seagal would be allowing the bad guy to reincarnate as a more peaceful being. Seagal agreed, and the scene went on as scripted. Unfortunately, Seagal later ad-libbed the line, "Thank God I didn't kill that guy..." Tobolowsky then had to record a few lines to make it seem like his obviously dead character had actually survived, like a bad horror movie monster. According to IMDb, however, those lines didn't make the final cut.
