Austin cast: Who stars alongside Ben Miller?
Everything you need to know.

Ben Miller returns to our screens in Austin, an eight-part comedy about an author embroiled in a social media controversy who is stunned when a man claiming to be his son turns up out of the blue.
Austin, the 28-year-old who claims Julian is his dad, is played by Michael Theo, who Miller first saw on Love on the Spectrum, a documentary series about people on the autism spectrum who are navigating dating and relationships.
"I was completely blown away by Michael," said Miller. "I thought he was extraordinary and such a fascinating person in the show and on screen.
"After bingeing the entire series, I asked [director] Darren [Ashton], 'Do you think Michael could act? I get the feeling he could.' And Darren agreed."
Miller went on to say that while he doesn't know if Austin has a "message... it feels very refreshing to watch and that is partly because neurodiversity is underrepresented on camera".
"It's really fun to see a neurodivergent character who's not Sheldon from The Big Bang Theory, and who in some ways is the opposite of that character," he said.
"One of the typical images of autistic people is that they're not very empathetic and they're not very good at human connection, but Michael's special gift is empathy and human connection."
