A reenactment of arguably the most famous shootout in the history of the American wild west turned dangerous Sunday when an actor accidentally shot himself in Arizona during a gunfight scene near the 'OK Corral.'

The Cochise County Sheriff's office says that an actor shot himself in the upper thigh on Sunday afternoon during a reenactment scene near the OK Corral.

The actor, who is a member of the Tombstone Vigilantes gunfight reenactment group, was reenacting the famous duel between Mexican outlaw Filemeno Orante and the old Wild West's Cochise County Deputy sheriff Kiv Phillips, Jeff Miller told the New York Daily News.

The unnamed actor who was playing the role of the sheriff shot himself in his groin during the stand-off and was airlifted to a Tucson hospital for treatment, according to authorities. His condition is unknown at this time.

A woman who was also hit by shrapnel refused medical treatment, Cochise County Sheriff's Office spokeswoman Carol Capas told Tucson News Now.

It's not clear how a real bullet made its way into the actor's pistol, but the group is taking extra measures to ensure an accident like this doesn't happen ever again.

'We've been doing this since 1947, and we've never had an incident before,' Miller told the New York Daily News.

'We have strict rules about that, so we're not sure how this happened. It's not something we take lightly.'

Miller added that the group's armorer checks each gun before the do a show to make sure there is no real ammunition inside.

The misfiring is being investigated by the Tombstone Marshal's Office.
