Originally planned to be an AMC original film for television, it was later announced that it would be a film trilogy with a wide theatrical release by Universal Pictures. However, due to the pandemic and the parent series concluding, it transitioned itself into a television miniseries.
Andrew Lincoln and Pollyanna McIntosh appeared on three series in the franchise. Both were in The Walking Dead and The Ones Who Live. Andrew made an appearance in Fear the Walking Dead, while Pollyanna was in The World Beyond.
