Kevin McKidd Says He Turned Down 'Big Villain' Character In Final 'Harry Potter' Films

Kevin McKidd plays a god in "Percy Jackson & the Olympians: The Lightning Thief." He almost played a monster in "Harry Potter."

While chatting with MTV News about "Percy Jackson & The Olympians: The Lightning Thief," in which he plays Poseidon, the Greek god of the sea, McKidd revealed that he was recruited for a meaty, villainous role in the "Harry Potter" franchise. A scheduling conflict prevented him from coming aboard.

"I was asked to be in the last two 'Harry Potter' films and I couldn't do it because I was busy filming 'Grey's Anatomy,' " McKidd said. "There was this mean, alpha-male werewolf character, who's like the big villain in the final film."

Our guess is the role McKidd was offered was that of Death Eater Fenrir Greyback. Only problem with that theory is Greyback was played by Dave Legeno starting in "Harry Potter and the Half-Blood Prince," not just in the final two parts of "Deathly Hallows." Perhaps McKidd was offered a role in the last three films, and he simply misspoke during the junket. His turn in "Grey's" began airing in the Fall of 2008, while "Half-Blood Prince" wrapped filming in the spring of that year, so it's possible there was scheduling conflict back in '08. Let us know your thoughts on McKidd's role in the comments below.

In any event, the Scottish actor's work as a trauma surgeon alongside Ellen Pompeo on "Grey's" prevented him from joining up with "Potter." His kids were not pleased.

"My kids were so pissed," he said. "They were like, 'Why did you have turn that down? I was like, 'I didn't turn it down. I couldn't do it.' But when ["Percy Jackson"] came through, it was like, 'I've got to do this because I've never done this kind of movie before.'"

Do you think McKidd would have been a good fit for Fenrir Greyback? Can you think of any other Potter characters he might have been offered?
