Rose Byrne: “We did a marriage counselling session in character, so I was doing my English accent and we were in our characters’ names and clothes and we were with a legitimate, certified marriage counsellor and we did a two-hour session and it was recorded - we said we were doing a documentary [laughs]. That was pretty early on that we did that. But that was good, it was fun.”

Dan Mazer: “Christ, I forgot about that…”

Rafe Spall: “Did you ever tell that marriage counsellor that we weren’t really a couple?”

Dan Mazer: “No…” [laughs]

Rafe Spall: “Well you have now… Dan was actually sitting in on the session because we were filming it, but this marriage counsellor thought she was just doing a session, and Rose and I were in character, and it was like two hours long wasn’t it?”

Dan Mazer: ”Yeah that’s before the movie started, and before we rehearsed and they went in and completely managed to come across as an authentic couple who were having problems to this marriage counsellor, who, obviously sees couples all day, every day…”

Rafe Spall: “Yeah, but Rose was doing it with an accent, it was extraordinary. I mean I was joking about her accents earlier, but I think her accent’s so good in this film…”

Dan Mazer: “Rose was annoyed that basically the marriage counsellor was siding with Rafe…”

Rafe Spall: “She got seriously pissed off…”

Dan Mazer: “Like properly annoyed. She just got so deep in character, just like, ‘I’m really annoyed the marriage counsellor is on Rafe’s side.’”

Rafe Spall: “The counsellor fancied me…”

Dan Mazer: “Who can blame her. She’s got urges, she’s got needs…”
