Shark! (also known as Caine and Maneater) is a 1969 American action film directed by Samuel Fuller and starring Burt Reynolds. The film was based on the Victor Canning novel His Bones are Coral with the original screeplay written by Ken Hughes. When Fuller joined the project, he rewrote the script and retitled it Caine.
Reynolds plays Caine, a gunrunner who becomes stranded in a small port in the Red Sea. He meets a seductive woman who propositions him to dive into shark-infested waters off the coast for scientific research. However, when Caine realizes the woman and her partner are actually treasure hunters, the action starts to heat up both above and below the water.
During production, one of the film's stuntmen was attacked and killed on camera by a shark that was supposed to have been sedated. When the production company used the death to promote the film, (even retitling the film to Shark!) Fuller, who had been arguing with the producers on several major issues relating to the film, quit the production.
When Samuel Fuller finally saw the version that was released to theaters, he said it was so badly butchered he demanded the producers take his name off it. The producers refused.
The film was re-released as Man-Eater by Legacy Entertainment Inc. in 2003.
