15 year old Oliver Tate is definitely a nerd. He's also arguably the closest any film has come to representing me at that age in cinema.

John Gordon Sinclair's loveable Gregory may not be a nerd in the traditional super-intelligent obsessive sense, but he's the gawky, gangly epitome of those awkward teen years where social interaction with the opposite sex seems impossible.
