Rose Byrne: “Dan had seen Bridesmaids and he approached me after that and said that ‘I really would love you to play this role and I think you could really do it, and we want this actor Rafe Spall.’”

Dan Mazer: “What was my first thought when Rose Byrne came aboard? I thought ‘Phwoarrr!’”

Rafe Spall: “’Phwoarrr…’”

Dan Mazer: “Not half… I should say so…”

Rafe Spall: “No seriously, I think she’s brilliant, I’ve long been a fan of her work, and she’s not only a brilliant dramatic actress and one of the great beauties of our age, but she’s a brilliant comedienne. She’s the full package.”

Dan Mazer: “Yeah, she really is. And it was amazing and I think I was writing this during the time Bridesmaids came out and I saw that and I just thought, ‘I have to work with Rose Byrne,’ and that was further underlined when I found out that that the brilliant scene in Bridesmaids where they’re making the speeches and they are trying to outdo each other, was essentially improvised between her and Kristen Wiig.

“I just thought if someone could be that beautiful and that funny…There’s no chance whatsoever they’re going to be in my film… [laughs] But I would really like them to, and - lo and behold - she read the script and liked it, and from that point on there was never any debate about who we wanted…”

Rafe Spall: “She’s a great laugh, she’s got a brilliant sense of humour, she’s the complete opposite to Nat really, she’s got a real sense of humour and she’s a laugher and I would just, I knew that if I was making her laugh during a scene, we were on the right direction really…”

Dan Mazer: “And she’s daring, she’s willing to take a risk which y’know, you don’t often find that with actresses of her calibre and who look like that, they often want to play it safer.

Rafe Spall: “The thing about her characters in Bridesmaids and this, they are completely different… completely different accents…”

Dan Mazer: “She’s got different dresses. It’s amazing, so versatile…” [laughs]
