Making an action-packed television show isn’t always fun and games.

E! Online reports that early on Friday morning, an accident on the set of Castle sent two to the hospital. The on-set accident is still being investigated.

Actress Karen David, who was filming a guest spot on the hit show, was one of the parties involved in the accident.

“Karen was the actress in the scene with the stuntman. They fell from a moving van when a door would not shut. Karen was in the emergency room for hours being treated. She has been released but is in serious pain and has to wear a neck brace,” talent manager William Blaylock said.

The stuntman involved in the accident with Karen is in serious condition and is being treated for head injuries.
