I see how Tom Wilson got the part!

If you've ever seen any of Tom Wilson's standup comedy, you'll understand how he must have been a shoe-in for the part of Biff. He even has a song called, "Stop Asking Me the Question" in regards to BTTF.

But when you see the breadth of his talent and how naturally it comes out of him, he probably did the part of Biff effortlessly. And not only is he talented but the guy is very brilliant when he does interviews and Q&A on a stage panel.
