Gabriel Byrne is set to star in The 33, the film about the trapped Chilean miners.
The Irish actor has signed on to play Andre Sougarret, the engineer who masterminded the extraordinary rescue operation of the 33 men and became famous with his updates about the search and rescue effort, reported Deadline.
Antonio Banderas is already on board to play leader "Super" Mario Sepulveda, with Rodrigo Santoro as one of the other miners. Martin Sheen has been cast as a father desperately waiting for news of his trapped son.
Juliette Binoche, James Brolin and Lou Diamond Philips also have unspecified roles in the movie, which is being directed by Patricia Riggen.
The 33, which tells of the tense 69 days in 2010 during which 33 miners were trapped following a collapse at the San Jose Mine in Chile, is filming on location in Colombia and Chile's Atacama desert.
Gabriel, who won a Golden Globe for his portrayal of Dr Paul Weston in US drama series In Treatment, will next be seen in blood-sucking fantasy Vampire Academy: Blood Sisters.
He will also star as Dublin's chief pathologist Quirke in BBC One's new drama Quirke.
