Bradley Cooper has revealed he loves revisiting his Hangover alter ego.
The Silver Linings Playbook star is currently shooting the third instalment in the lads on tour trilogy, in which he plays party-loving Phil.
Bradley confessed: "It is actually easy to get back into Phil. It's a nice sort of place to go to. I love Phil."
When asked if there's anything he does to get back into character, the heartthrob quipped: "I just grow my hair out, and bam, all of a sudden I'm there."
Bradley stars alongside Jennifer Lawrence in The Silver Linings Playbook, the latest flick from filmmaker David O Russell.
He said working with David has helped him prepare for directing his own film one day.
"There's no question that he allowed me to work with him in a way that was like going to film school for me," he added.
