Tennant played DI Alec Hardy in the hit whodunnit’s first run, and will appear a lead role in the US remake, Gracepoint, alongside Breaking Bad star Anna Gunn and Aussie Jacki Weaver.
“David’s very busy and Alec Hardy, at the end of series one, he was fired from the police, he had a heart problem – I don’t see how you come back,” Chibnall told Radio Times.
“[David is] a king on the stage, he’s off doing an American show right now… he’s got a lot on his plate.”
Last year, Tennant stated that he was unsure of his future with Broadchurch, saying: “I was dying of a heart attack so I don’t know how able Alec Hardy will be to do any more crime-fighting, we will have to see.”
Meanwhile, Tennant also appears in Spies of Warsaw on SBS ONE.
