London: British heartthrob Colin Firth enjoyed "making a fool" of himself in the hit musical `Mamma Mia` and now finds dignified roles boring.
The actor, who appeared in the romantic musical alongside Pierce Brosnan and Meryl Streep, enjoyed making the film as none of them ever took it too seriously, reported Contactmusic.
"I think dignity can be a little overrated. I just relished making a fool of myself along with all these rather serious actors," he said.
"Every time we finished a take, we would look at each other and blanch. There was a fantastic kind of recklessness to it. What on earth were we doing? Committing career suicide? That audiences liked it was very gratifying. Really, it`s one of the experiences I regret least in my life," added the actor.
Firth who starred in blockbusters including `Bridget Jones`s Diary`, `Love Actually` and `The English Patient`, said that lack of chemistry between the stars can make films a "misery".
"It can be utter misery. Because you are trying to manufacture something that`s supposed to be happening naturally," he added.
