Charlie Bartlett is the hero in the 2007 American film Charlie Bartlett. He is a teenager who helps the other students in his high school. Charlie is an 18 year old white male, has curly brown hair, and has a very charismatic personality. He gets along with almost anyone he meets. He wears typical male teenage clothing such as solid-colored/patterned t-shirts, brown blazer, blue jeans, and black high-top sneakers. During the film, he eagerly transitions from white briefs to loose dark-colored boxer shorts for two major reasons: to increase his popularity with other students as he dispenses advice in the boys bathroom and to be more attractive to Susan, the principal's daughter.
