Academy Award nominees Josh Brolin and Jeremy Renner are set to headline A Speck in the Sea, a survival thriller directed by Oscar-winning filmmaker Orlando von Einsiedel, known for the documentary short The White Helmets. The upcoming film is scripted by Oscar-nominated writer Jeff Pope, who co-wrote Philomena and The Lost King.

Based on a true story, A Speck in the Sea follows Johnny Aldridge (Brolin), a Montauk lobster fisherman who falls overboard in the middle of the Atlantic Ocean one night in 2013. His best friend and fishing partner, Anthony Sosinski (Renner), is asleep below deck when the incident occurs. Upon waking up to find Johnny missing, Anthony sets off a multi-state rescue operation, while Johnny fights to survive in the open sea using every survival skill at his disposal. The film is produced by Mark Bauch of One Day's Walk and Jonathan Eirich of Rideback.

Brolin is best known for his performances in Milk, No Country for Old Men, American Gangster, Inherent Vice, Sicario, Avengers: Endgame and Dune. He is also set to return for the upcoming third instalment of Sicario.
