9. Jeremy Irons - Dungeons & Dragons
For the most part, Jeremy Irons has had a respectable acting career. I say "for the most part" because, for some unexplainable reason, he was featured in the painfully awful 2002 movie Dungeons & Dragons. They actually made two sequels (without Irons): one made-for-TV and the other direct-to-DVD. Both have higher IMDb ratings than this one. That's how bad it was. Despite a host of reasons why it was terrible, you could almost forgive Irons for not realizing just how bad it would turn out. After all, it's based on a very popular role-playing game. If nothing else, he might have expected a fair amount of story and character development. Probably even some impressive special effects. Unfortunately, it had none of those things. What did it have? Marlon Wayans. Yeah.
