Lily Cole says playing an old lady in 'Snow White and the Huntsman' ''all got a bit deep''.

The model-turned-actress - who stars alongside Charlize Theron and Kristen Stewart in the upcoming fairytale adaptation - revealed getting into character was a ''bizarre experience''.

The 24-year-old star said: ''It was a very bizarre experience. I watched the make-up artists apply it and it was certainly very surreal. I started thinking, 'What will I be like as an old lady, physically and mentally?'

''It made me quite reflective and quite sad actually - it all got a bit deep.''

Lily plays a young girl transformed into a haggard old lady by the evil Queen Ravenna, and she confessed working alongside Charlize and Kristin was a ''huge pull'' in accepting the role.

She explained: ''I loved the strong, female characters and The Script is such a page-turner. It's a very dark take on something everyone knows so well. I was so keen to work with Rupert Sanders, the director - he's so intelligent and talented.

''And Charlize was a huge pull - I'm a big fan of her work. And Kristen was great to work with too - I hadn't actually watched 'Twilight' before I started the film. I never approached it in terms of 'how can I learn from these people', but perhaps you do in subtle ways.''

Lily - who has previously starred in 'The Imaginarium Of Dr Parnassus' alongside the late Heath Ledger - has big plans for her future in film.

She added to ''I'd love to work with Judi Dench and Marion Cotillard.''

Lily was in Cannes for the 65th Annual Film Festival yesterday (22.05.12) promoting her latest film, 'Confessions of a Child of the Century', with co-star Pete Doherty.
