David Tennant is unlikely to return for a second series of Broadchurch
, according to the show's writer Chris Chibnall.
Tennant - who played DI Alec Hardy in the first series of the ITV crime drama - has already agreed to appear in Gracepoint
, the US remake of Broadchurch
Chibnall told the Radio Times
: "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."
The former Doctor Who
star recently returned to the stage to appear in the Royal Shakespeare Company's production of Richard II
at The Barbican in London.
"[David is] a king on the stage, he's off doing an American show right now... he's got a lot on his plate," Chibnall added.
Tennant's co-star Olivia Colman has confirmed that she will be reprising her role of Ellie Miller in the new series.
A return date for Broadchurch
has yet to be announced by ITV.
