The Deep (1977): Robert Shaw was paid $650,000 plus a percentage of the profits. Bissett and Nolte were paid $200,000 each.
The character of lighthouse keeper and diving and treasure expert Romer Treece (Robert Shaw) was inspired by real-life treasure seeker diver Teddy Tucker, who helped Peter Benchley write the novel. Tucker was hired as a special consultant to the production, and appeared in the movie playing The Harbor Master.
Author Peter Benchley can be briefly glimpsed as one of the U-boat shipmates in the prologue of the longer version of the film. The roles of the young Treece and Coffin were played by the sons of Robert Shaw and Eli Wallach.
