Hugh Grant said most of his films leave him feeling "suicidal".
The 'Love Actually' actor told how when he has saw the first cuts of a number of his films - which include the hugely successful 'Bridget Jones's Diary' and 'Notting Hill'- he felt so bad about his performances he wanted to die.
He said: "Normally, when I see the first cut I'm suicidal. I want to go to that euthanasia clinic in Switzerland, Dignitas, and have myself put down."
Despite his negativity, the actor was pleasantly surprised when he saw an early version of his latest film, comedy 'Did You Hear About The Morgans?' in which he stars alongside Sarah Jessica Parker.
Hugh, 49, added: "This film looks a lot better. This one is quite beautiful."
The self-proclaimed "reluctant actor" has threatened to quit Hollywood many times and to give up acting, even claiming he was semi-retired after appearing in 'Bridget Jones: The Edge of Reason' in 2004. He said the reason is because he "freezes up" in front of the cameras.
He explained: "I like everything about filming except the acting. I'm wonderful in rehearsals, but I have never been very good when they actually switch the cameras on.
"In recent years I've had really bad attacks where I totally froze up. I thought, 'Well, if I am going to get stage fright, then I am packing it in.' "
He did, however, add he would not consider joining the theatre.
He added: "I'm not suited to the theatre. I get bored after the first week."
