London, May 19 : British actress Mischa Barton has come a long way since her days as Marissa Cooper on the US TV series `The O. C.'.

Barton, 23, sheds off her clothes for a scene in the new movie `The Assassination of a High School President'.

In the scene, she sheds off all her clothes for a dip in the tub.

She leaves little to the imagination as she gets close to her naked co-star, reports the Sun.

Meanwhile, according to reports, the film has been put on hold due to the lack of money on the distributors part. (ANI)
