The 18-year-old actor, who plays Carl Grimes in the AMC television horror drama, said the eighth spell is going to be "really fun", reported Contactmusic.
"Season seven was all about building up and getting everyone ready to fight against Negan and this season, there's going to be lots of explosions, lots of killing, a lot more Negan (played by Jeffrey Dean Morgan).
"Yeah, lots of fighting. Lots of cool stuff. It's really, really fun this season," Riggs told Triple J.
