Few TV thrillers have been favourably compared to Tarantino, the Coen brothers and Wes Anderson but Two Brothers Pictures’ ambitious six-part Boat Story, starring Daisy Haggard, Tchéky Karyo and Paterson Joseph, is no run-of-the-mill action series.

This multi-layered show, which started its run on BBC One in late November, begins conventionally enough, with Janet (Haggard) out walking on a wintry Yorkshire beach. However, the down-on-her-luck Janet discovers a washed-up boat containing two dead bodies and cocaine worth millions.

In series one, we joined The Man, who we now know is Elliot Stanley, just before he suffered complete memory loss after being driven off the road by a truck.

Together with probationary constable Helen Chambers, who first questioned Elliot about the crash, they set off on a search for his identity.

By the end, however, Elliot was wracked with guilt having made some damning revelations in regards to his life before the crash, which also turned Helen away.

Daisy Haggard and Paterson Joseph embark on new BBC thriller Boat Story

Harry and Jack Williams have written the series and will also produce under their award-winning All3Media company, Two Brothers Pictures (Fleabag).

Daisy Haggard and Paterson Joseph will star as two hard-up strangers, Janet and Samuel, who stumble across a load of cocaine on a shipwreck.

They can't believe their luck, but after agreeing to sell it and split the money, they quickly find themselves entangled with police, masked hitmen and a suited-and-booted gangster known only as 'The Tailor' (Tcheky Karyo).

The cast and creators of Baptiste discuss the upcoming final series

“We didn’t want him to become another police officer… We’ve told big, bold stories that gave [Julien Baptiste] a proper journey – he doesn’t just come in and find out some stuff and go home,” said Jack, the older of the Williams brothers by two years. “It’s about doing the right thing for the show and the characters.”

Jack Williams – plus brother Harry and the actors Tchéky Karyo and Fiona Shaw –were speaking at an RTS event previewing the new series of Baptiste, chaired by the critic and broadcaster Rhianna Dhillon.
