After three seasons on HBO’s In Treatment, Gabriel Byrne is returning to UK TV to star in a four-part drama series for Channel 4. With the working title Coup, the Company Pictures/Newscope Films conspiracy thriller starts production in February and will air later this year. Byrne will play politician Tom Dawkins, a reluctant hero thrust into the spotlight following an industrial disaster that raises questions about the safety procedures of the U.S. petrochemical company involved. Dawkins risks everything by taking on the establishment in his pursuit of the truth, uncovering a web of secrets along the way. The series is based on the novel A Very British Coup by Chris Mullin and was adapted for the screen by Robert Jones. Ed Fraiman is directing with Johann Knobel (Shameless) producing. Executive producers are Jason Newmark, Fraiman, George Faber and Charles Pattinson.
