Having looked up information on him, I can't help but wonder if Scotty Beckett suffered from bi-polar disorder or something. Back then, there was no name for it and God forbid anyone address taboo subjects like addiction and mental illness. He was obviously intelligent and talented, but couldn't steer himself off of a self-destructive course. His behavior later in life alienated a lot of people and he's somewhat forgotten today, which is sad. At least we have his work to remember him by.
He's adorable in this movie!
