The Walking Dead, one of America's most-watched cable shows, is based on a series of Robert Kirkman graphic novels, and screens on TV2 in New Zealand.
It finished the first half of season five on Monday, and will be back in February.
Meanwhile, Curtis will realise another dream when he competes in the IronMaori half-Ironman in Napier today.
Curtis, 46, will do the 2km swim leg for the three-person Team Mo, put together by singer Moana Maniapoto, in line with the kaupapa of the One Heart Many Lives health project.
Ms Maniopoto will take on the 21km run and the 90km bike ride will be done by George Bradfield, husband of Ngati Kahungunu songstress Hinewehi Mohi.
Curtis (Te Arawa, Ngati Hauiti) had been set to do the run for Ms Maniapoto's Te Arawa Tri-Hards in 2012 but was a late withdrawal because of work commitments in Prague.
Mr Bradfield replaced him at the time and reported the actor was "gutted" not to be there.
Curtis was unable to be contacted about the event, but his entry was confirmed by event founder and organiser Heather Skipworth.
Despite a quarter-century in television and movies and a series of startling action roles, he apparently also harbours some trepidation about Saturday's 8am thrash in Pandora Pond, Miss Skipworth revealing: "He's a bit nervous."
Ms Maniapoto said on Facebook: "Pleased that he was spouting our mantra 'completing, not competing'. Surviving is what it's all about. Says he might be the only one in the pond wearing floatie devices. He said he's perfected the art of dog paddle."
