<P>Bradley Cooper has revealed he loves revisiting his Hangover alter ego.</P>
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.
