Hangover 2, the highly anticipated comedy sequel faced a setback last week when a stuntman was severly injured in a car accident.

Scott McLean, a prolific figure in the film industry for his stunt work on set was rushed to Bangkok hospital and is reportedly in a special care unit. He has done numerous stunts in big blockbusters including the Matrix and Star Wars

While not many details have been revealed about what went wrong, Warner Bros issued a statement after the incident:

"The truck and car were both driven by stunt drivers. An ambulance immediately took the injured stuntman to the local hospital, and he has since been transported to a hospital in Bangkok, where advanced care is being provided. We are awaiting further details concerning his condition." CBSnews

Hangover 2 faced controversy before shooting when its film crew allegedly snubbed Mel Gibson because of his tirade earlier in the year.

US President Bill Clinton was then cast in the cameo rule, an unpresidented move to shore up the film, which is set to be released in May 2011.
