‘Sherlock’ star Benedict Cumberbatch in talks for new Meryl Streep movie

Actor to play Streep's nephew in the film version of award-winning stage play 'August: Osage County'

Sherlock star Benedict Cumberbatch is in talks to join the Hollywood adaptation of award-winning stage plage August: Osage County.

The high-profile movie has a cast that already includes Meryl Streep, Julia Roberts, Juliette Lewis, Abigail Breslin and Dermot Mulroney. It will be directed by John Wells, best known for his work on ER and the US remake of Shameless and counts George Clooney among its producers.

The original play by Tracy Letts, which ran on Broadway and at London’s National Theatre in 2008, follows a dysfunctional family who are brought back to their childhood home by a crisis. According to The Hollywood Reporter, Cumberbatch is being lined up to play the nephew of Streep’s character, a “sensitive” soul who finds out that the identity of his real father had been hidden from him. Filming will begin in Oklahoma next month (2012).

Cumberbatch, 36, is best known as the star of BBC1’s Sherlock, a role which recently earned him an Emmy nomination. His big screen CV includes War Horse and Tinker Tailor Soldier Spy and he is set to play the villain in the currently untitled Star Trek sequel.

Last month (July), Cumberbatch revealed that he will make a cameo appearance in the next series of The Simpsons, which is scheduled to return to US screens next month (September). His next UK TV appearance will come in Parade’s End, a World War One miniseries which begins on BBC2 at 9pm tonight (August 24).
