Cameron Diaz believes that director Kirk Jones had the hardest job on What To Expect When You're Expecting.
The actress takes on the role of a pregnant fitness instructor in the comedy movie alongside Matthew Morrison, Jennifer Lopez and Elizabeth Banks.
The movie follows five different women as they cope with pregnancy and impending parenthood. And Diaz thinks that the weaving together of these stories was the toughest part of this movie.
Speaking at the UK press conference for the movie the actress said: "What he had to do was the most difficult part of the film and that was to weave all of stories together seamlessly and make them feel that they were relevant and not just because they were all pregnant at the same time.
You needed to be able to go from one story to the next, even if they didn’t have anything to do with each other, and still like you were in the same film and he did that amazingly.
He is doing movie, movie, movie he is shooting five different movies in a period that you would shoot one whole movie in so it was an interesting challenge for him."
What To Expect When You're Expecting is the first movie for Diaz since the success of Bad Teacher last year.
However she has also completed work on Gambit, a remake of the 1966 movie as Diaz teams up with Oscar winner Colin Firth.
What To Expect When You're Expecting is out now.
