Brad Pitt can't stop thinking about death.
Since shooting "The Curious Case of Benjamin Button" - in which he plays a man who is born old and ages backwards - Brad has been obsessed with dying.
Brad, 45, said: "I walked away realising that time is short.
"I don't know if I have a day or ten days or 40 years. Am I halfway or am I close to then end? I don't know, so I have to make sure I don't waste those moments in any kind of pettiness or bitterness or laziness, and that I surround myself with the people who are most important to me."
Brad - who raises six children with his partner Angelina Jolie - also admits the multiple Oscar nominated movie has taught him to cherish every day.
He added to Britain's Daily Telegraph newspaper: "Angelina and I are together because we can enhance each other. I don't want to waste any time because I'm with company I really, really love."
