Ryan Reynolds has described his experience on the set of new low-budget thriller "Buried" as his worst - because he spent 14 days locked in a seven-foot-long wooden 'coffin.'
The actor plays a U.S. truck driver who is kidnapped in Iraq and buried alive with only a cellphone and a lighter for company and spent two weeks rolling around in the dirt and sand underground in Barcelona, Spain.
He admits the shoot left him unable to sleep and desperate for a getaway with his wife Scarlett Johansson when filming wrapped.
He tells Entertainment Weekly magazine, "I never slept, and it was a real problem. I was just so wound up. I was totally alone out there.
"Very few crewmembers spoke English and coming home at the end of each day was kind of a lonely, anxiety-ridden experience.
"I'd planned a vacation about six months beforehand to leave from the set and join my wife on this sandy beach, but there was so much sand in the box. I realized the last place I wanted to go afterward was a place filled with sand.
"I've never been happier to finish a movie. I will never complain on a film set again."
