There's been no official word on a second series of Humans - but star Will Tudor thinks the show has the potential to run and run.

Tudor told Digital Spy that the writers behind the Channel 4 drama have plans that extend beyond the first 8-part series.

"I really hope it continues - as much as a viewer as someone who's in it," said the actor, who plays malfunctioning android Odi.

"It explores things that I've personally not seen on screen before, and it raises a lot of questions. In the first series, there were a couple of things where I thought, 'Ooh, what about that?' and 'What if that happened?'

"I think the writers have got a lot more they want to tell, that's all I'm going to say!"

Humans launched as Channel 4's best-rated drama in over 20 years, with Tudor admitting that he "knew it would be popular" and reach a mainstream audience.

"Sci-fi can be a cult genre," he said. "But with this, I think it's so much about the relationships that it moves way beyond sci-fi.

"I think also it plugs into fears that everyone has. These 'Synths' are so eerily human, it really raises the question of what it means to be human - and that's a massive question."

Set in a parallel present where robot 'Synths' are considered a common household appliance, Humans has charted the relationship between inventor George Millican (William Hurt) and Odi (Tudor) as the latter breaks down through old age.

The inspiration for his performance? "I tried to look at my old Windows 95 computers, and my old phones, and what happened when I'd had them for too long," he revealed.

A second series of Humans is "very much under consideration", according to Channel 4's head of international drama.

"We've got a story that is told over a great many episodes and is very much designed to come back and return," said Simon Maxwell. "We'll be following those characters on a really epic journey."

Humans continues this Sunday (July 26) at 9pm on Channel 4.
