The scar on Brittany Snow's forehead is real although it is more pronounced in the film. On her scar Brittany stated, "I got my scar when I was 3 years old from falling on a brick. My sister was babysitting me and forgot she was babysitting me and then I fell and tripped and split my head open. I chose not to get plastic surgery on it. I chose to embrace it. Now, I think it adds character. I like it."
