Knightley and Damon set for 'Tender Is The Night' roles

Keira Knightley and Matt Damon look set to star in a movie version of F Scott Fitzgerald’s 'Tender Is The Night'.

David Nicholls, who wrote the scripts for 'Starter For 10' and 'Simpatico', has adapted the screenplay and 20th Century Fox has offered Keira and Matt the lead roles, according to Pajiba.com.

The story follows the psychological disintegration of a young married American couple on the French Riviera in the 1920s.

Damon would play Dick, a promising young doctor living off the money of his wealthy wife Nicole, played by Knightley.

There is currently no director attached.

The book was previously adapted for the big screen in 1962.
