The zombie drama is currently on hiatus, but will return to AMC in the US and FX in the UK in early 2012.
"I can say that in the second half, after this hiatus, people are done talking," Reedus told Daemon's TV. "It's all kind of firecrackers from here on out. It gets more action packed."
However, the actor defended the pace of season's two initial seven episodes, insisting that the show's characters "have to talk".
"I know when people watch the show they go, 'More zombies. More death'," he admitted. "But you have to do a bit of talking. Otherwise it's Transformers."
Reedus also suggested that a romance between his character Daryl and grieving mother Carol (Melissa McBride) is unlikely.
"We do have a sort of special bond, and it's not so much romantic as I think it's damaged people hanging out with damaged people," he explained. "They sort of gravitate towards each other. I even find that more interesting [than a romance].
"As far as a romantic thing, I have no idea if that's in the works. I think it's almost more interesting that it doesn't happen, to be honest."
The Walking Dead returns on February 12 in the US.
