John Goodman surprised everyone at the premiere of his new film Trumbo in London last night, but it wasn't because of anything he did on screen!

The 63-year-old showed off his noticeable weight loss, looking fitter than ever in a pin-striped suit and purple shirt.

The father-of-one has previously joked about his weight, telling People magazine, "It takes a lot of creative energy to sit on your ass and figure out what you're going to eat next."

But in 2011, the actor got serious with David Letterman, admitting that at his heaviest, he was "pushing 400 lbs."

While John hasn't revealed how he managed to slim down this time, he's shed pounds in the past by cutting out sugar and alcohol, as well as working out six days a week.
