Hollywood star Tom Cruise revealed he has no qualms about going topless on screen, despite his age.

The 'Mission: Impossible' actor, who celebrated his 50th birthday last July, bares his top half in his latest film, sci-fi epic 'Oblivion'.

"I don't get embarrassed, I just do it," he said at the film's UK premiere at London's BFI Imax.

No embarrassment here... for Tom Cruise, at the UK premiere of sci-fi film 'Oblivion'

Cruise, who plays Jack Harper in Joseph Kosinski's film, said he has no plans to retire from the screen in the near future.

"I've been offered a number of times to (direct). But I love acting and I enjoy the process of working with the director," he said.

"I started producing films just because of my love of it and I wanted to create stories that they weren't making. So no, but I will act for the rest of my life."

Tom Cruise wows co-star Olga Kurylenko

His co-star Olga Kurylenko, in a Marchesa dress and Salvatore Ferragamo heels, had only compliments for her leading man.

"I was nervous about meeting him at first but when I met him, he was so open, kind and welcoming. Tom is a generous partner. And he lights up the room with his energy," she said.

Kosinski, who also directed Tron: Legacy, added: "He is the hardest working man I've ever met."

Morgan Freeman and Andrea Riseborough also star in Oblivion, which opens in cinemas on 10 April. Watch Tom Cruise on the notion of bubbleships below...
