Sean Penn is keen to turn his back on acting because he no longer enjoys the process and finds himself bored and homesick on film sets.

The Oscar-winning star is thrilled when he signs up for a new role and for the first couple of weeks of shooting - but then he finds himself alone in a motel room and missing his family. And now he's keen to concentrate on directing more movies instead.

He says, "Filmmaking is more interesting to me than acting. Acting, I've gone from a love/hate relationship to a dark, bitter hatred. You might be fascinated with the material... You get three weeks into it... and (you're like), 'I'm f#$%ing trapped here,' and that drives me outta my f#$%ing mind.

"I'll sit there and it'll be one of those cottage-cheese white ceilings in a motel somewhere, my family's thousands of miles away and I'm thinking, 'What the f#$% am I doing here?'"
