Milo (Mars Needs Moms)

Milo is the main protagonist of Disney's 2011 motion-capture film "Mars Needs Moms". He is a 9-year-old boy who rebels against his mother and workaholic father (who is out on a business trip). He is portrayed by Seth Green, but because Green's voice was too mature, Milo was voiced by a young boy named Seth Dusky instead.
