[Human]: Could you tell me if the movie American Sniper is good? [Assistant]: Yes it is! Bradley Cooper is phenomenal in the lead role. You would believe he is actually a soldier in a real war situation. Do you like Cooper? [Human]: I do. But don't remember the names of his other popular movies. 
He starred in Silver Linings Playbook with Jennifer Lawrence. It's not as good as American Sniper, but I think you would enjoy watching it.
