Los Angeles, Apr 10 (IANS): Scottish actor Gerard Butler says his fans wish he does more action films, but he admits he enjoys working in all types of movies.

The 44-year-old actor has worked in romantic films like "P.S. I Love You", "Playing for Keeps" and "The Ugly Truth". But his fans want to see him in action films.

"More people tend to say, 'Why the **** don't you stop doing love stories? If I see you in another love story I'm going to put a knife through your brain,'" femalefirst.co.uk quoted Butler as saying.

"I have done a few romantic comedies until they're coming out of my ****. But I really enjoy making them. I really enjoy making all types of movies," he added.

In his latest movie, "Olympus Has Fallen", Butler plays an army ranger turned secret service agent who must save the President - played by Aaron Eckhart, from a terrorist attack on the White House.

When he watched the final edit, he admits he was shocked to see how violent his character Mike Banning was.

"I didn't realise how many knives to the brain there were before I watched the movie. Then I was like, Holy f**k! I don't seem to kill anyone in any other way!' But it's a pretty effective way to kill somebody," he said.
