Scottish actor Ewan McGregor says he is frightened by "Star Wars" fans and their devoted fervour for the sci-fi saga.

The 34-year-old actor, who plays the young Obi-Wan Kenobi, found working on the three "Star Wars" prequel movies uninspiring as they focused more on special effects than performance. But he is even less enthusiastic about the films' die-hard enthusiasts, reports the Internet Media Database.

"There's this huge following, which is weird. They have big meets and conventions, and I find it all a bit frightening," McGregor said.

"Once this guy met me at a stage door when I was doing a play in London. The guy yelled, 'Obi-Wan. Do you have any advice for a trainee Jedi?' I just said, 'No, don't be so ridiculous.' It's just so weird, it really is."
