Susan Sarandon is set to star in 'Snitch'.

The 'Enchanted' actress will appear alongside DWAYNE 'THE ROCK' JOHNSON in the action thriller, which has been written by Ric Roman Waugh - who will also direct.

The movie tells the tale of a father who goes undercover to bust a big-time drug dealer to reduce his son's 30 year sentence in prison, and Susan will play an ambitious lawyer who wants to take part in a drugs bust to help boost her career in politics.

It is based on a documentary previously shown on Frontline.

Nigel Sinclair, Guy East and Alex Brunner are set to produce the picture alongside lead star Dwayne, Dany Garcia and David Fanning, according to The Hollywood Reporter.

Susan - who won an Best Actress Oscar for her performance in 'Dead Man Walking' in 1995 - recently finished filming comedy 'I Hate You Dad' with Adam Sandler, and 'Gently Down the Stream' with Robert DeNiro.

She is also attached to 'Cloud Atlas' - which also stars Tom Hanks, Jim Sturgess and Halle Berry - which is due to be released in October 2012.
