The first film not only introduces the characters, but also shows the initial rivalry between Stuart and Snowball. This movie also shows how the different characters get used to Stuart's "special needs". The movie features a toy boat race with Stuart captaining the Little's entry as well as a run-in with some mean alley cats. But ultimately, Stuart learns what it means to be a part of a family through loyalty and friendship.
Stuart Little 2 shows the little mouse as he is going through some growing pains. This movie introduces another one of the classic book's characters, Margalo. In the movie, the little canary is being chased by a falcon and Stuart saves her. When Stuart invites her into the Little home, he starts to count her as a friend. But when it seems like Falcon has taken her, it's up to Stuart and Snowball to find the little bird and get her back safely. But there are a couple of twists and turns along the way. This movie adds actress Melanie Griffith as Margalo and actor James Woods as Falcon into the Stuart Little cast list.
Stuart Little 3: Call of the Wild is definitely the odd one out in this collection. The most noticeable difference is the fact that it is done in an animated/rotoscoping format (which might have been done purely to show that Lipnicki is not playing George). This movie shares the same theme as the first two: it doesn't matter how big you are, only how big you feel. In this chapter, the Littles move to a summer lake house and George and Stuart join the Lake Scouts with their dad taking the role of assistant scout leader.
Stuart's size quickly becomes an obstacle as he has trouble tying knots and rowing a canoe across the lake, and when all of the other scouts (including his big brother) advance to the higher ranks and he is left behind, Stuart starts to get discouraged.
Eventually Stuart befriends a local skunk, Reeko (played by Wayne Brady, Who's Line Is It Anyway) who teaches him the ins and outs of living in the woods. And Stuart will have to put all of his new knowledge to the test when the local legend "The Beast" gets the notion of snacking down on Snowball.
Though these three movies don't really duplicate the classic E. B. White story, they do pull a lot of inspiration from the book.
