John Goodman has had an up-and-down weight loss journey, but now he’s looking fitter than ever.

The actor, 63, showed off his new, slimmer look at the Trumbo premiere in London Thursday night, giving his costars Bryan Cranston and Adewale Akinnuoye-Agbaje some competition in the who-looks-best-in-his-suit department.

Goodman has been open with his weight struggle over the years, previously joking with PEOPLE, “It takes a lot of creative energy to sit on your ass and figure out what you’re going to eat next.”

The 6’2″ actor admitted to David Letterman in 2011 that his weight tends to fluctuate and that he was “pushing 400” lbs. at his heaviest.

Previously, the actor said he lost weight by cutting sugar and alcohol from his diet and working out six days a week.
