The movie is to premiere April 1. The 100th anniversary of the maritime disaster, which happened after the luxury liner hit an iceberg, is April 14.
"Everyone knows about the many deaths in the icy waters, the fates of the rich and famous on the ship's maiden voyage and the dramas that played out in the Titanic's last hours," a synopsis said. "What is less known is how a team of shipbuilders and engineers attempted to save the stricken vessel. One hundred years after the sinking of the vessel considered unsinkable, 'Saving the Titanic" is the untold story of self-sacrifice and dignity of the ship's engineers, stokers and firemen in the face of impending death."
The cast includes David Wilmot, Ciaran McMenamin, Owen McDonnell, Jonathan Byrne, Andrew Simpson, Hugh O'Conor, Douglas Rankine, Paul Kennedy, Stephen Hogan, Conor MacNeill and Chris Newman.
