Marcella recently returned for its third season on ITV, changing the premise from being about a policewoman mother to being an undercover agent in a whole new environment with different characters.
With creator Hans Rosenfeldt proving that he doesn't believe a show's formula needs to be set in stone, is there the possibility of a fourth season or a spin-off set in the same universe to mix things up even more?
"I haven’t even though about (season 4) yet, to be honest," Hans exclusively told Digital Spy.
"Because there is, as I’ve said, no obvious thread to say, 'Let’s start there. That was interesting'... In a good way, you can do anything, basically. And in a bad way, there’s nothing to spark your imagination into, 'Oh, that would be fun.'"
But while he thinks that the season 3 finale "is an ending this time", he also suggested that some characters have spin-off potential, specifically the larger undercover operation.
"You could do the story around them," he said, "like a Godfather thing. But from the characters we brought in, I would say that Frank is possible, because he’s in charge of those undercover operations.
"And the people he’d bring in – apparently, since he brought in Marcella – are maybe not the most suitable for it.
"So I think he’s a fun character. His whole organisation of undercover cops all over England or abroad – that’s a possible spin-off. But I’d say that’s probably it."
Marcella is available to watch now on ITV Hub.
