Stuart Little 3

Stuart Little 3 is a 2005  American live-action/CGI animated film directed by Rob Minkoff. It stars Geena Davis, Hugh Laurie, Jonathan Lipnicki and Virginia Madeson alongside the voices of Michael J. Fox, Nathan Lane, Melanie Griffith, Kevin Spacey, Wayne Brady and Steve Zahn. Taking place three years after the second film, the plot follows Stuart Little as he reunites with Margalo where both of them are in a crisis wondering what their real purpose is in life apart from being as big as they feel. When they get captured by a retired vet, family cat and alley cat Snowbell and Monty along with their new friends West Highland Terrier Bobby (Kevin Spacey) and black and white skunk Rico (Wayne Brady) go on a journey to Canada to rescue them, hoping they don't get dissected by the vet.
The film was originally envisioned as a full animated direct-to-video release because of the box office performance of Stuart Little 2, however when the script proved promising, Columbia Pictures decided to upgrade the film to a live action CGI hybrid theatrical release.
==Story==
Three years after the events of the second film, Stuart Little starts to ask himself about how to find a purpose in life after he gets off for the summer. He's come to terms with knowing that he's as big as he feels, however he feels that he wants to stretch his muscle and try something that he feels that he can do. Snowbell at that point in time is just relaxing and doesn't know why Stuart feels the need for adventure, he keeps telling him that he's got one year left of school before he tries to pull any impressive stunts. George says the same thing to Stuart, there's a whole new world out there of jobs and hobbies, he's just not ready to experience them yet. 
After getting a call from a long lost cousin, Fredrick Little (the father of the family) announces that they'll be going on vacation to Montana to visit the cousin.
