But before he became a star on both the big and small screen, the 35-year-old actor financially struggled to the point of being homeless.
On Friday, Pratt shared with fans the very same Scooby-Doo van he used to call home.
"Can't believe I found this picture!!!" he shared on Facebook. "That is the van I lived in!!! In my hand is the script for the movie that got me out of Maui. Crazy." The script is believed to be from the 2000 short horror movie, Cursed Part 3.
In recent interviews, Pratt has shared details about his financial situation before making it big in Hollywood. After dropping out of college after one semester, the actor went to the island and worked a string of odd jobs.
"It's a pretty awesome place to be homeless," he told The Independent. "It would be different if I lived on the streets of Chicago and ate garbage from a dumpster."
But while working at Maui's Bubba Gump Shrimp Company, Pratt found himself facing a special customer. It was actor-director Rae Dawn Chong who eventually gave Pratt his first significant role.
Today, Pratt is back working on his NBC comedy and loving life with wife, Anna Farris, and their son, Jack.
Talk about a true Hollywood success story!
