The Guardians of the Galaxy star was riding the motorbike when the brakes locked up as he drove through some mud, causing him to be thrown 20 feet (six metres) across the set.

Panicked crewmembers rushed to his side to check on their leading man, but Pratt had to urge them to step back and give him a little room so he could get back to work.

He tells The Associated Press, "That one really jolted me. I was immediately swarmed by everyone. When you're on a movie and that much money is on the line, should your star get hurt...

"I'm like, 'Listen dudes, you've got to back the f**k off for a second. Am I fine? How could I possibly know that? Give me a day and I'll tell you. It seems OK right now.'"
