According to the press release for this film, Emma is part of the cast, playing a character named Lucy and apparently it's a smaller role than her previous ones so she won't have to film as much and should have an easier time squeezing in filming in her schedule. However, surprisingly we have yet to hear from Emma or her reps regarding this role, despite her being mentioned in the press release. I assume that if the information were incorrect we would have heard something by now, so I assume she is in the movie. Hopefully we hear more about this role soon.
