Game of Thrones and Ripper Street actor Jerome Flynn is set to star in the new BBC thriller, The Trick.

The cast for the 90-minute film also includes Jason Watkins from Line of Duty, Victoria Hamilton (Doctor Foster,) George MacKay (1917) and Adrian Edmondson (Save Me.)

Filming is expected to begin soon in Cardiff, London and Norfolk.

"With time running out against an unseen enemy, The Trick looks at the potentially devastating consequences to humanity from climate change denial; how a media storm undermined public confidence in the science and how the concept of 'truth' took a back seat causing us to lose a decade of action," a synopsis said.

"The film also charts the unjustified persecution of Phil Jones, his wife Ruth's fierce support of her husband and the fight for the ultimate exoneration of himself and the science."
