Hollywood actor Woody Harrelson is desperate to get back to comedy acting after his stint of serious roles, because he loves to make people laugh.

The EDTV and CHEERS star, who is currently performing in London's West End as a Reverend in Tennessee Williams' play The Night of the Iguana, admits he has had moments wondering why he decided to undertake such a serious role.

He says, "I said to myself, 'What am I doing in this play? It's so dramatic.'

"You just want to make people laugh sometimes.

"I'm not looking for credibility. Respect would kill me!"
