The actor, who plays gun-toting Daryl Dixon in the zombie series, filmed a short video in the aftermath of the Connecticut school massacre in December (12) to remind viewers of the dangers of automatic weapons.
In the clip, which has been shown before episodes of the horror show, he says, "Everyone at The Walking Dead and Amc (network) are deeply saddened by the recent events in Connecticut. In light of this tragedy, we want to remind you that The Walking Dead contains some intensely violent scenes. While the show takes place in a fictional world, parental and viewer discretion are strongly advised."
The clip was first aired in early January (13), and Reedus has now revealed he received an outpouring of support from fellow stars when he attended the recent Golden Globe awards.
He says, "(I received) a tonne of support... A lot of actors came up to me (at the Golden Globes) and said they thought it (the video) was great, which was a real surprise to me because I had no idea they were even watching the show."
Reedus goes on to insist American politicians need to tighten the country's gun laws to prevent another massacre like that at Sandy Hook Elementary School, where gunman Adam Lanza shot dead 20 children and six adults.
He adds, "I don't feel there's a real reason to have automatic weapons at all. I can understand the right to bear arms to some extent, but no one needs an automatic Ak17 (gun) hanging in their truck. No way."
