Fortunately, according to an AMC spokesperson, the injuries turned out to not be life-threatening, and the injured production member has already been released from the hospital. No details were provided on who the production member was or how the injury occurred.
While the zombies might not be real on The Walking Dead, action shows require extensive stunt work, so on set injuries are always a risk. Even though production was halted due to the accident, filming has since resumed, and an AMC spokesperson said the upcoming season would not be affected.
The Walking Dead Season 4 premieres on Sunday, October 13, 2013 on AMC.
