Colin Farrell has come clean about the accident that almost brought filming of Oliver Stone's flop epic Alexander to a halt - he drunkenly jumped out of a window.

The Irishman previously claimed he broke his ankle and wrist after falling down some stairs at a cast party staged by co-star Val Kilmer, but the truth is tougher to believe.

He recalls, "I fell much farther."

In retracing his drunken steps from the night before after waking in pain in a tent in the middle of a field, he realised he leaped from a bathroom window.

He adds, "I remember DENIS (CONWAY - co-star) saying, 'I think you jumped.'"
