Samantha Barks can't believe she's in a Hollywood film.

The theatre actress - who was once a contestant on Andrew Lloyd Webber's reality show, 'I'd Do Anything' - stars alongside an all-star cast including Hugh Jackman, Anne Hathaway and Russell Crowe as Eponine in 'Les Miserables', but still can't fathom how her fortunes have changed since landing the role.

Speaking to OK! magazine, she said: "I still can't believe this is my job. I've started a diary because so much is happening and I want to remember every detail.

"It was overwhelming. It was a huge gamble to cast me because I didn't have any screen experience. I remember going on Twitter [when it was announced] and reading all these messages of support. I think I wrote something like, 'I am just in tears at this time'."

The 22-year-old beauty was starstruck when she found out she'd star alongside Sacha Baron Cohen and Helena Bonham Carter, who play her character's parents in the Tom Hooper-directed musical.

She recalled: "When I first heard I was going to be playing their daughter I was like, 'What?!' They're the coolest on-screen parents I could ever have. I think they are incredible."

Having gotten a taste of the big screen filming 'Les Mis', Samantha wants to follow in co-star Hugh's footsteps, by going from stage to screen permanently.

She added: "It's definitely made me hungry for film. The dream is to combine it with musical theatre. It can be done - look at Hugh Jackman. He started on stage and built an incredible career in the theatre and then moved onto film. He is inspiring to me as somebody who made that work."
