"I would definitely be up for a cameo!" Watson told MTV News in LA.

Reuters: "Noah" marks your return to large-scale spectacle films, do you approach your role any differently than you did while making the "Harry Potter" series?
Emma Watson: I remember being on set and Darren was saying, "Okay, the water is going to be cold, we're probably going to be here for a full day, try and conserve your energy between takes, like keep warm and make sure you eat properly. This is going to be physically very demanding." For a minute I felt very intimidated and then there's something about having done those "Harry Potter" films and they were very physical. We did a lot of stuff in Scotland. It was freezing cold, filming at four in the morning, working crazy hours.

Did you do any reading on your character of Ila outside of the script?
Emma: I actually didn't do a lot of reading, but I did a lot a research because I become a mother in the story, and obviously have never given birth myself. That required quite a lot of careful thinking. Darren and I had this conversation where we both agreed that in so many films, women give birth and it looks like they're barely breaking a sweat. We wanted it to feel very raw, very real and so I took it pretty seriously.

Did you talk to anybody about what it's like to give birth?
Emma: Any pregnant woman anywhere, I'd be like, "Can I talk to you? Can I talk to you about your experience?" I spoke to my own mother a lot, obviously, and then I watched a lot of YouTube videos of natural births, lots of documentaries, spoke to midwives, just any information I could get my hands on, really.

Ila is unable to conceive initially, but then is made fertile by a miracle. Was there anything in particular you tried to emphasize of her psyche?
Emma: I guess just her self-doubt. ... Ila is barren, she can't have children, and she doesn't want to deprive her future husband of being able to have kids and to have a family. There's this real wrestling match within her. She's so in love with him and she kind of sacrifices her own happiness for his, and that struggle and self-doubt felt very relatable to me.

AP: You followed the "Potter" films with a string of indies. What was it like to have "Noah" put you back in big-budget territory?
Watson: I think there's value in these bigger-scale projects because, obviously, they have this incredible scope. ... But then it's so lovely to work on a more intimate scale and do those kinds of films as well.

AP: Did stepping into the world of "Noah" make you consider your own take on religion?
Watson: I already had the sense that I was someone who was more spiritual than specifically religious. ... I'm really interested in those things that are more far-reaching than culture, nationality, race, religion.

AP: You'll get your degree in English lit from Brown in May. Are you excited?
Watson: I will be having a hell of a party. It will just be a relief, I think, because I've been really juggling so much and it will just be really nice to be able to focus on just one thing but I think I'll miss it, too.

AP: You've made the transition from child star to adult actress look easy, and we know it can be challenging. How'd you do it?
Watson: You know, it can be a very corrupt environment and situation for a young person and I'm just so thankful that I have people around me who have really held my hand.
