Wow, John Goodman, where did you go?

The "10 Cloverfield Lane" actor showed off his incredible weight loss this week before catching a flight in Los Angeles.

For years, John was one of the more rotund actors in Hollywood, but that has all changed over the last several years.

John has previously admitted that he was once close to pushing 400 pounds. Those days are long gone now.

He's lost well over 100 pounds from his heaviest point which was in 2007.

Last year, John's fitness coach Mackie Shilstone said John did it the old fashioned way — it was all about diet and exercise.

"This didn't happen overnight — it's been an ongoing process," he told the New York Post last year. "There needs to be strategic planning. This time, he really wanted to do it."

The trainer said John's slow transformation began after he stropped drinking in 2007. He then changed up his diet and stuck to a "Mediterranean-style eating plan."

He also got busy in the gym. John, according to Mackie, broke a sweat six days a week and tried to take at least 10,000 to 12,000 steps a day. He also began to be a bit of a gym rat, working out on the treadmill and elliptical.

John has struggled with his weight for years. After losing an astonishing 100 pounds by 2010, John began gaining the weight back by 2013. However, he decided to get back to the regimen that initially took the weight off and started eating better and working out.

Just like last time, it's working.

In 2010, after losing the weight the first time, John told People magazine, "I know it sounds sappy, but it was a waste. It takes a lot of creative energy to sit on your ass and figure out what you're going to eat next ... I wanted to live life better."

In that same People interview, Mackie, who also has worked with Serena Williams in the past, said, "[John] remembers what it feels like to be extremely heavy and it's something he doesn't want again."

He continued, "John is very agile. When I see him running I get out of the way! He can be a different type of actor now. He can take on athletic parts."
