Rose Byrne says she's been "in awe" of her comedy castmates while making Bridesmaids.
Speaking at the Breakthrough Of The Year Awards in Los Angeles, the Damages actress revealed: "I think comedy is so much harder than drama so I'm just in awe the whole time, figuring out how they work.
"I just finished the movie with Kristen Wiig, it's a really funny female comedy."
She added: "It's hilarious and I had a great summer doing that."
Hollywood comedy master Judd Apatow is helping produce the film.
"He's brilliant," Rose revealed. "I did Get Him To The Greek last year with those guys and he's very collaborative."
"It's a very relaxed environment," she added.
Little Britain's Matt Lucas and The IT Crowd's Chris O'Dowd star alongside the actress in the funny flick.
"I'm honoured to be there," Rose admitted.
