'Walking Dead' Star Josh McDermitt: Success Can Be a Pain in the Ass

"The Walking Dead" star Josh McDermitt says the popularity of the show is a blessing, but it's also a curse.

Josh was amazingly candid, showing his frustration that the show is so insanely popular, producers have to go to extreme lengths to protect plotlines ... specially, who was killed in the cliffhanger.

There are reports the show has individually shot death scenes with every main character so no one knows which will actually air when the show comes back in October.
