In the 1st film, George did not feel comfortable with Stuart as his brother because Stuart's size torpedoed his dreams of a brother he could wrestle and play other boy sports with. However, eventually the two of them bonded over participating in a model boat race, which ironically they would have lost if not for Stuart's height - or lack thereof.
George has blonde hair, and he usually wears a light orange long-sleeved shirt, blue jeans, and red and white sneakers. His hobbies include skateboarding and models of all kinds.
In the first and second film, he was portrayed by Jonathan Lipnicki, who also played Ray from Jerry Maguire, and Tony Thompson in The Little Vampire. In the third film, he was voiced by Corey Padnos. In the TV series, he was voiced by Myles Jeffrey.
