Olivia Colman has revealed how grateful she is to Paddy Considine for letting her play against type in his film Tyrannosaur.
The actress, who is known for her comedy turns in Rev and Peep Show, plays a victim of domestic violence in Paddy's critically-acclaimed debut feature film.
Speaking at a screening of the film at London's National Film Theatre, she described the role of Christian charity shop worker Hannah as "a gift".
She said: "It's a part I've always wanted to do and it was brilliant that Paddy had some imagination to let someone weird do it. I've dreamt of this whole job and this part since I was about 12 and he made it happen, so it was terrifying, I didn't want to let him down."
Olivia and Eddie Marsan, who plays her sadistic husband, contacted the charity Refuge to help them prepare for the roles.
The actress added: "Eddie is the nicest man in the world but can play terrifying very easily, it made my job easy."
