Bradley Cooper knew he and his 'Aloha' co-star Rachel McAdams would have ''great chemistry''.

The 'Wedding Crashers' co-stars have reunited for Cameron Crowe's new movie and the 40-year-old actor was delighted to find the 36-year-old actress even better to work with than he remembered.

He told 'Entertainment Tonight': ''I knew that we would have great chemistry.

''At least I thought we would based on 'Wedding Crashers', a movie I'd done with her 10 years ago. I always thought, 'Wow! It's so easy to work with her.' She's so present and it only got stronger after 10 years.''

Meanwhile, Rachel enjoyed working with Bradley because he is so passionate about the project.

She gushed: ''It's such a wonderful thing to come to work with Bradley every day, because he has so much passion for not just his character but the whole film - the whole process.

''He approaches every scene like he wants it to be the best scene filmed ever.''

The pair are joined in the film - which sees a military contractor screw up a deal, forcing him to return to Hawaii, where he tries to romance both an old flame and a young air force pilot - by an all-star cast including Emma Stone, John Krasinski, Alec Baldwin, Danny McBride, Jay Baruchel and Bill Murray.
