She's fast heading towards the big 4-0.

But there's no denying Kate Beckinsale is still quite the knockout.

The actress, who turns 38 on Tuesday, delighted her fans last night as she put her incredibly long legs on display in a short black dress at the Comic-Con fan convention.

The British star was joined by her husband Les Wiseman, the director of her new film - a reboot of the 1990 hit Total Recall starring Arnold Schwarzenegger.

She as at the event to promote the movie, which also stars Jessica Biel and Colin Farrell.

Farrell also took to the stage for a panel discussion about the movie in which he play Doug Quaid, the same role originated by Arnie in the original.

Farrell's description of his character's arc echoes what the actor has experienced in his own life: 'I loved the idea of a man journeying from being a man in a deep, deep slumber to consciousness,' he said.

He described his character's battle in the film as one between the intellectual and the emotional.

Director Wiseman said that while his version is totally different from the first film, it also draws from the original source material: Philip K. Dick's story 'We Can Remember It For You Wholesale.'

Besides Farrell, the film stars Bryan Cranston, Bill Nighy and John Cho. It is set for release next summer.

Comic-Con continues until Sunday at the San Diego Convention Centre.
