John Goodman shows off impressive weight loss

Oh hey there, John Goodman! The Trumbo star has been busy hitting red carpets to promote his new film, and Goodman, 63, has never looked happier – or healthier, for that matter.

Just look at the difference a year makes.

Whatever he's been up to, it's working! Goodman's all smiles. Although who can blame him, when Helen Mirren's around??

Here's Goodman talking to David Letterman about his weight struggles in 2011.

Goodman shared that at his all time high the actor was "pushing 400" pounds.
