Leonardo couldn't make it but we do get to meet the main men behind the scenes - the director, the writer, the scriptwriter and the producer of The Beach.
We have gathered for a special screening of "another film about an impoverished childhood," as John Hodge, the screenwriter, jokes. Three of them are the film-making musketeers, who famously first joined forces for Trainspotting, and they are together again.
Forget sun-bathing in Thailand where The Beach was shot, says Andrew Mac- Donald, its producer. "The heat is hellish. I don't like it," he says, pulling up his sleeve to reveal a snow-white forearm. Oh, my God. Are we expected to check for needle tracks? "I'm very pale, I was about the one man who didn't tan." Oh, whew.
As for filming in and under water, it's a case of don't mention the war because "it takes forever" what with tides and so on.
And the sharks? "There are sharks but they're not dangerous. More people die from coconuts falling on their heads in Thailand," he says. Still, after the screening, Lord Henry Mount Charles says the film is "a mixture of Lord of the Flies, Apocalypse Now and Jaws."
Alex Garland, writer of the book on which the film is based, is here as well, as is the director, Danny Boyle.
Others in glitzy gear who are out for the night's entertainment include Marion O'Dwyer, co-star of Agnes Browne and Claudia Carroll, of RTE's Fair City. Victoria Smurfit, who has a part in The Beach, is unable to talk "apart from telling you I had a wonderful time". Sure, that's all we wanted to hear.
