In the clip, Jessica Biel hints at the past romance between her and Bradley Cooper's character and figuring out who was to blame for the turmoil.
"We sort of leave it kind of to the imagination as to where it could go at the end of the film. We give you a little hint about who did who wrong, but I think we both feel that we're right, " says Biel.
Later on in the clip, Cooper speaks on getting prepared for his character and what he had to consume to get in better shape.
"I've just been sort of on this crazy, getting in shape regimen...not crazy shape but just sort of believing that this guy could do stuff. So that's been a lot of fun; no salt or sugar. That's been GREAT! I just eat what they put in front of me but it's a lot of like boiled chicken, brown rice and broccoli," Cooper explained.
