Underworld star Scott Speedman once rushed to the aid of an intruder who fell from his roof.

The actor is grateful he doesn't have to worry about obsessive fans, but admits he has had odd encounters with devotees of his cult Tv series Felicity and vampire versus werewolf action franchise.

And one superfan really got a little too close for comfort.

He tells Playboy magazine, "I had a guy fall off my roof a couple of years ago. He'd been in the house - that was a little creepy - but when it happened I was just sitting around.

"I heard a crash and ran outside. He knew my name... He had separated his shoulder, and he asked me to pop it back in.

"I'm like, 'Well, no, let's wait for the professionals.'"
