Filming began this month on the four-part series, which follows Simon, a regular family man who makes a split-second decision that changes everything. The episodes are each an hour long.

A group of teenagers begin terrorising the neighbourhood, with Joe Barber playing 17-year-old ringleader Jordan Franklin. Simon and his wife Beth, played by Claire Skinner (Outnumbered), are desperate to move their daughter somewhere safer. Instead, Simon confronts Jordan outside his house, where a single lapse in judgement sends his life into a tailspin.

Also appearing in the cast is David Bradley (Game of Thrones), who plays Simon and Beth’s grumpy neighbour Harry. Kayla Meikle (Small Axe) appears as DS Kelly, and David Mumeni (Stath Lets Flats) as Simon’s boss Jimmy.

“Coma is a provocative thriller that asks the audience: What would I do? It's the story of a good man who does one bad thing that causes his life to spiral out of control,” said Paul Testar, commissioning editor for Channel 5 and Paramount+.

The show is created and written by Ben Edwards (Shameless) and directed by Michael Samuels (Any Human Heart).

Coma is produced by Roughcut Television and CBS Studios, with distribution being handled by Paramount Global Content Distribution.

Coma will air on Channel 5 in 2024.
