The shooting of upcoming movie The Hangover Part II was halted on a routine basis as the cast and crew battled sickness and made regular trips to the hospital.
 
Stars of the original 2009 movie, including Bradley Cooper, Ed Helms and Zach Galifianakis, reunited to film a sequel about a hazardous bachelor party in the hedonistic city of Bangkok, Thailand.

However, the three-month shoot proved to be more difficult than director Todd Phillips imagined as his actors and crew members were hospitalized for a variety of conditions ranging from exhaustion to food poisoning.

He tells Total Film magazine, "It ended up being a battle of endurance and we lost people all the time to food poisoning, heat exhaustion... everybody, including all the actors, were in hospital for some time... My movies are about mayhem and I always think I like it, but Bangkok is mayhem to another degree. You're shooting and guys will literally drive through the scene on their little motorcycles. It was hot, it rained a lot. It feels like we went to war!"
 
Cooper adds, "I have a lead stomach so I never threw up. Bangkok is Vegas on steroids. Ed (Helms) got really sick. He was addicted to those charcoal pills (for stomach pain)."
