Mark Bomback (“Unstoppable”) is diving into “Shadow Divers” and will pen the true-life adventure for Fox 2000 with Scott Free producing.

The studio picked up rights in 2004 when it paid $500,000 against $1.5 million to acquire Robert Kurson’s historical deep sea adventure “Shadow Divers: The True Adventure of Two Americans Who Discovered Hitler’s Lost Sub.”

Story centers on the divers who in 1991 discovered a wrecked German U boat sunk alarmingly close to the New Jersey shoreline. The two men dove to depths approaching 230 feet — the limits of human endurance — to solve the mystery of how it wound up there. Both suffered great losses in the course of solving the mystery: a ruined marriage and the loss of friends’ lives on the wreck.

“Unstoppable,” produced by Scott Free and directed by Tony Scott, opens Nov. 12 with Chris Pine and Denzel Washington starring.

Bomback’s work includes “Race to Witch Mountain,” “Live Free or Die Hard,” “Deception” and “Godsend.” He recently completed work on Universal’s “The Umbrella Academy,” New Line’s “Agent Zigzag,” Fox’s “Protection” and an adaptation of Richard Ford’s novel “The Sportswriter” for director James Mangold.

He’s repped by WME and Anonymous Content.
