Three Men and a Bride?

Evidently, there is a new "Three Men" movie in the works (see MTV). IMDB says the movie will probably be released in 2012. This is quite exciting! Three Men and a Baby and Three Men and a Little Lady we two of my favorite movies when I was young. Steve Guttenberg, Tom Selleck, and Ted Danson--what a great trio!!! Question is: Who will play grown-up Mary? I think these could maybe fit the role--Emma Watson, Anne Hathaway, Jessica Alba, Mandy Moore, or Rachel McAdams. What do you think?
