Oscar winner Kevin Spacey has officially quit his acting career, to concentrate on his position as boss of a London theatre. The star insists he is sick of the Hollywood system and has enjoyed more than enough acting success. Spacey - artistic director of the Old Vic Theatre - says, "I don't care about my personal acting career anymore. I'm done with it. After 10 years of making movies and going better than I ever could have imagined, I sort of had to ask myself: 'What am I supposed to do with all of this success that I have had?" "Am I just going to keep making movie after movie and be concerned with all of that 'Are you up, are you down, are you hot, are you not?', and I don't really care. "What I really care about is the remarkable experience of being able to be a part of bringing people together."
