So many big-name actors got their start in horror. Tom Hanks did it with 1980's He Knows You're Alone. Jennifer Aniston had her first lead role in 1992's Leprechaun. But in 1983, future Hollywood heavyweights George Clooney, Charlie Sheen, and Laura Dern came together to be in the same horror movie, with it being the film debut for the former two. The movie was Grizzly II: Revenge, an intended sequel to 1976's Grizzly, but filming was shut down before it was completed, and the film was never released. That finally changed in 2021 when fans got to see the young future stars together for the first time, and what we saw was one of the most hilariously bad movies ever made.
