Woody Harrelson saved Jennifer Lawrence from choking on the set of 'The Hunger Games: Mockingjay - Part 2'.

The 52-year-old actor reportedly performed the Heimlich manoeuvre on the Oscar-winning actress when a vitamin got stuck in her throat on the set of the science-fiction adventure movie.

A source said: ''Jennifer had just downed a handful of her daily vitamins, swallowing them with water, but one got caught in her throat. Suddenly she started gagging, gasping, pointing at her throat as her face turned bright red. Everyone around her froze, not knowing what to do. But when a crew person screamed, 'Help,' Woody quickly ran up behind Jennifer and gave her a swift, hard slap on the back. When that didn't help, he wrapped his powerful arms just under her chest, gave two quick, strong squeezes, and the vitamin popped out of her mouth.''

The blonde beauty thanked her co-star for saving her life and admitted she was worried she was going to die.

A source told the National Enquirer that she was overheard saying: ''You literally just saved my life. I really couldn't breathe... I really thought I was gonna die right there.''
