Helena Bonham Carter has revealed that Colin Firth does nothing but talk.
The pair star as husband and wife King George VI and Queen Elizabeth in Ton Hooper's new movie The King's Speech.
And while Firth's character may be struggling with a stammer in the movie the actress admits he had not trouble talking when he wasn't in character.
Speaking to the Press Association the actress said: "I did find it funny that as soon as the camera was turned on he'd have difficulty speaking [playing a stammerer] but as soon as it's off, honestly, he just talks for Britain!"
Geoffrey Rush is also on the cast list and Carter went on to reveal that the pair did nothing but talk.
"They talk non-stop so it was kind of hard to concentrate. They're both amazing - they should have their own chat show!"
The King's Speech is already grabbing a lot of awards attention and Colin Firth has been tipped to pick up the Best actor Oscar later this year.
The King's Speech is released 7th January.
