'Elegy for Iris' Movie Poster Edition

Kate Winslet has arrived at the premiere of her new film with a new man on her arm - her younger brother Joss.

The 26-year-old actress, who is dating American Beauty director Sam Mendes, wore a revealing white jacket and black trousers as she arrived for the UK premiere of Iris.

Also starring Dame Judi Dench and Jim Broadbent, it is the love story of novelist and philosopher Iris Murdoch and her husband John Bayley.

Winslet plays the writer in her early days as a young novelist and Dame Judi is the novelist in middle age through her descent into Alzheimer's disease until her death in 1999.

Winslet said of the role: "It is hard because Iris was such an intellectual and I am not and when you have Dame Judi portraying her in later life it is quite frightening and you know there is a lot to live up to."

She added: "I would suggest people going to see it take a box of tissues as it will make you laugh, but will also make you cry."

Winslet said she had brought her whole family along for support. "My brother is my date tonight," she said.

Also present at the premiere was Weakest Link host Ann Robinson, who is the vice president of the Alzheimer's Association.

She said: "I like this film because it shows that clever people also suffer from Alzheimer's. It happened to my mother who had a very sharp brain but deteriorated terribly."

Others attending the screening at the Curzon Cinema in London's Mayfair included Cherie Blair and her son Euan, Nigella Lawson and Harry Enfield.
