20 Worst Performances In Superhero Movies

14. Julian McMahon (Doctor Doom) - Fantastic Four

Fresh off his success on hit FX show Nip/Tuck, Julian McMahon was cast as Victor Von Doom in Hollywood's first big-budget Fantastic Four movie, and on paper, he seemed like a fine fit for the part.

Devilishly handsome and cutting a great figure in a swish suit, McMahon nevertheless made for a weirdly boring Victor, failing to use his considerable charisma to make the audience truly care about him at all.

Things got worse when he became Doctor Doom, though, speaking with a curiously tepid voice that didn't prove remotely intimidating, and having little of the intense physicality that such an iconic role requires.

It's a shame McMahon didn't go full ham with the part, because his more restrained effort ended up being a total snoozer.
