She's gone from London-based soap opera EastEnders to the leading role in a Hollywood TV show Bionic Woman.

As Michelle Ryan marked her latest foray in movies in the newest 'Brit flick' The Man Inside, the actress made a nod to old Hollywood with a Marilyn Monroe-style dress.

The North Londoner, 28, went for retro glamour in a white sun-dress and beehive as she joined her co-stars at the London premiere of the boxing drama.

Joining her at the Vue Leicester Square were co-stars Ashley Thomas, Peter Mullan, Theo Barklem-Biggs and Ray Panthaki - who also starred in EastEnders.

Also on the red carpet was current EastEnders stars and real-life couple Jacqueline Jossa and Tony Discipline.

The Man Inside stars Thomas as a boxer, Clayton Murdoch, trying to distance himself from his gangster father (David Harwood).

Michelle plays recovering drug addict Alexia, who grows close to the young boxer as he is being trained by her father Gordon Sinclair (Mullan).

Meanwhile, the actress recently laughed off speculation she would return to EastEnders.

Her character Zoe's on-screen mother Kat Moon (Jessie Wallace) returned to Walford in 2010 after a five-year absence.

But Michelle is adamant she won't be reprising her role again after she left the soap in 2005.

She said: 'It's like I wouldn't go back to school. I just believe that sometimes in life you're like a shark - you have to keep moving through water otherwise you'll die.

'For me, once I've worked on something and it's finished, it's like an ex-boyfriend: you don't go back to them. I've done it with my heart and soul, so I wouldn't go back because it's not part of my make-up to do so. I think it's important to do different things.'

Instead, Michelle is focused on training for the West End production of Cabaret, which sees her play Liza Minnelli's character Sally Bowles.
