Why I think Corbin is PERFECT for the role of Issac...
Think about Issac's character. Successful kid model, trying to get back into the modeling game as an adult but keeps on getting rejected because he "isn't quite right." All of you guys' comments about how Corbin doesn't look like a model actually validates the reason why he should be in that role. If a more modelesque guy were playing the role of Issac, it wouldn't be as realistic.
