Byrne and Faris join romcom cast

Rose Byrne and Anna Faris are set to be the leading ladies in romantic comedy I Give It A Year.

The comic actresses will star alongside The Mentalist's Simon Baker and Rafe Spall in the forthcoming movie, which Dan Mazer has written and is directing, Variety reports.

Damages star Rose and Rafe will play a mismatched couple, who are struggling to survive their first year of marriage, while Anna and Simon have roles as "strong supporting characters".

Rose - who proved her comedic chops in Bridesmaids opposite Kristen Wiig and Maya Rudolph - will next be seen in Derek Cianfrance's crime Drama The Place Beyond The Pines with Ryan Gosling and Bradley Cooper.

Anna, who has become the queen of romantic comedies following her turns in Just Friends, My Super Ex-Girlfriend and The House Bunny, will next appear in the Sacha Baron Cohen comedy, The Dictator.
