EXCLUSIVE: Jason O’Mara (Sons Of Liberty) has been cast alongside Jamie Dornan (Fifty Shades Of Grey) in Richie Smyth’s Jadotville. O’Mara will play Company Sgt. Jack “Sarge” Prendergast, Dornan’s right-hand man. The film is based on the 1961 siege of an Irish UN battalion by 3,000 Congolese troops led by French and Belgian mercenaries working for mining companies.

Irishman O’Mara can be seen this summer starring in USA Network’s Complications. The 10-episode original series from Burn Notice creator Matt Nix follows John Ellison, a disillusioned suburban ER doctor who finds his existence transformed when he intervenes in a drive-by shooting, saving a young boy’s life and killing one of his attackers.

O’Mara also recently starred as George Washington in History’s miniseries Sons Of Liberty. He is repped by UTA, Independent Talent and Jackoway Tyerman.

Netflix acquired worldwide rights to Jadotville, which Alan Moloney produces for Parallel Films. Richie Smyth directs from a screenplay by Kevin Brodbin.
