British beauty Thandie Newton gets ruffled up, wearing a pink Matthew Williamson confection to the premiere of Picturehouse’s Run, Fat Boy, Run held at the Arclight Theatres on Monday in Los Angeles.

The 35-year-old actress was accompanied by director David Schwimmer, costar Simon Pegg and Picturehouse president Bob Berney.

Thandie has also recently been working with Madonna’s husband, Guy Ritchie, on Rocknrolla. She revealed to MTV that Guy is intent on turning his latest drama into a trilogy of films.

“RocknRolla is one of three films and Guy’s keen to get going on that straight away,” Thandie enthused. “[The second and third films in the series] are going to be excellent. I can’t wait. We shot incredibly quickly [on the first]. There were three weeks pre-production. He just gets on with it. He absolutely does not see challenges as intimidating.”

Also starring Gerard Butler, Jeremy Piven, and Ludacris, RocknRolla is a game of “follow the money,” said Newton, as it connects to a variety of disparate and needy characters.
