The new Jamie Dornan movie The Siege of Jadotville has proven to be a massive success at the Galway Film Fleadh.

The 50 Shades Of Grey actor co-stars with Jason O’Mara in the Netflix war drama that revolves around the siege of 150 UN Irish troops led by Commandant Pat Quinlan (Dornan) in the Congo in 1961.

"This is the first official viewing of the film," said a Fleadh spokesperson ahead of Saturday night's screening. "The demand for tickets was phenomenal and we could've sold out the venue three times over.

"Unfortunately, Jamie Dornan isn't available to attend the screening, but that hasn't stopped the phone from ringing constantly with inquiries for tickets that are long sold out."

In The Siege of Jadotville Dornan plays the army officer whose men held out against a force of 3,000 local troops led by French and Belgian Mercenaries working for the mining companies.

Guillaume Canet, Emmanuelle Seigner, Mikael Persbrandt, and Mark Strong also make up the cast.

Directed by Richie Smyth, the film is adapted from Declan Power’s The Siege at Jadotville: The Irish Army’s Forgotten Battle.
