(Cover) - EN Movies - Anna Kendrick has joked about the awkwardness of working out the "logistics" of her romantic scenes with Chace Crawford for their new movie.

The pair play old flames Marco and Rosie in the upcoming comedy drama What to Expect When You're Expecting. Their characters reunite and Rosie ends up getting pregnant.

Anna has laughed off feeling uncomfortable about the intimate scenes during the first meeting between the cast and crew.

"Our craft is our life so we really took it to the next level. I was like, 'We should make out a lot more in this movie, it's important,'" she deadpanned.

"Even in one of the first rehearsals, one of the first things that came up was the logistical element of us kissing on the car, and we're in this hotel conference room doing this very first rehearsal meeting everyone for the first time and that was the first order of business.

"[British director Kirk Jones] kept saying 'bonnet' and we were like, 'What are you talking about? It's the hood.’"

Anna is a big fan of the hugely successful fantasy franchise Harry Potter. The star has revealed her favourite movies out of the eight-strong series.

"Oh, it's tough. Everybody says Prisoner of Azkaban is their favourite, but it's not for me. I think four was a turning point because that's where it started to have that level of realism. It didn't look like Tim Burton, it looked like a Rembrandt. It looked like it took place in the real world," she told Collider. "I think five actually was even better."
