Hey big suspenders! Sienna gets to grips with saucy new role

Welsh actor Matthew Rhys enjoyed an extremely warm welcome in the hillside while filming scenes for a new movie with two of the sexiest stars of British cinema.

As our revealing pictures prove, the 32-year-old looks like he’s comfortably getting to grips with his new role as poet and fellow countryman Dylan Thomas, alongside Keira Knightley and Sienna Miller.

Shall we dance? Sienna wraps a leg around Matthew's waist while filimng a steamy scene for the film.

That looks like wheelie good fun: Sienna gives her co-star a lift.

Sienna and Kiera share a joke as they relax while filming the biopic about Dylan Thomas.

Sienna replaced Lindsay Lohan in the role of Thomas's wife after the troubled American withdrew from the movie, called The Best Time of Our Lives.

And the couple certainly stayed true to the film’s title while acting out a raunchy dance scene that puts Heather Mills’s tame moves firmly in the shade.

And in another steamy scene, Keira reportedly joins the pair for a hot and heavy threesome between the sheets.

A source said: "Everyone was gutted when Lohan quit. We knew love scenes between her and Keira would pull in the punters. But when Sienna said she wanted the role our fears were laid to rest. The sex scenes will go down in movie history."

The film is sure to be a box office hit when it goes on general release next year - as long as lucky old Rhys has enough energy to make it through to the end of filming.
