Details about the upcoming animated Smurf movie are trickling in slowly. We learned Friday that Neil Patrick Harris will play the only live action character in the movie and today we have three new names attached to the film.

Singer Katy Perry and the future Mrs. Russell Brand will provide the voice of Smurfette.

Alan Cumming will voice Gutsy Smurf with Papa Smurf being played by Jonathan Winters who is now 84-years-old and who was featured in the original Eighties cartoon.
