Jack Nicholson and co-star Morgan Freeman paid tribute to the late actor Heath Ledger at their new film 'The Bucket List's London premiere last night.
The tragic premature death of the Australian 'Dark Knight' and 'Brokeback Mountain' star dominated the evening.
Freeman said: "It's a great loss to the industry. He was an enormous movie talent. It sounds like a tragic accident."
Post-mortem tests on the 28-year-old were inconclusive but speculation has mounted that he died from an accidental overdose of sleeping pills.
He recently admitted taking the prescription drug Ambien to combat insomnia.
'The Bucket List's director Rob Reiner added: "It's unbelievably sad. I directed a film ('Stand by Me') with River Phoenix. He also died at a young age. It's so tragic when someone dies at that age, for life to be cut short."
Asked about Ledger's death, Nicholson said: "Wasn't that horrible."
Reports have suggested that Ledger may have found playing the Joker role in the new Batman film too much, and that the part left him unable to sleep.
But asked about the role, which Nicholson also played, the veteran star simply said: "Oh the Joker role..."
Ledger was found dead with pills near his body at his New York apartment on Tuesday.
