Nightsleeper is a six-part British television series made for BBC One, starring Joe Cole and Alexandra Roach and written by Nick Leather for Euston Films.

[1][2] It was revealed in December 2022 that the BBC had commissioned the series written by Nick Leather who is also executive producer alongside Gaynor Holmes for Euston Films.

In Watson's estimation, Joe Cole "does a kind of low-rent Speed-era Keanu Reeves turn" but nevertheless made "a fine action hero", while the passengers aboard the hacked train were "little more than clichés with issues, their backstories inserted to fill in the bits between chases/near misses/staring at the rail-route map.

"[14] In Radio Times, David Craig gave the series two stars out of five, saying it was "laden with cliché in terms of dialogue and plot structure [...] taking several staples out of the bland conspiracy thriller playbook" and "compromised by the sheer volume of jokes, which go beyond comic relief to almost rendering this show an outright comedy-drama."

Craig would finish his review by saying the series felt "like a show that couldn't decide what it wanted to be", with "shades of a self-aware train-set action-comedy, dashes of a nervy cyber thriller, and attempts at hard-hitting social commentary on political polarisation and marginalisation.

Leigh concluded that the series "did manage to maintain a sense of urgency and pace in spite of the flaws but perhaps was a little too eager to prove itself as a gripping mystery thriller.
