The Sharkfighters

The Sharkfighters is a 1956 American adventure film about U.S. Navy scientists working to invent a shark repellent to protect military personnel down at sea. Directed by Jerry Hopper, it starred Victor Mature, James Olson, and Claude Akins. The fictional storyline is based on the invention of Shark Chaser, an historical shark repellent developed by researchers during World War II.

Duncan approaches Ben and asks for a transfer to sea duty, but relents when Ben asks him to postpone the request, which he would have to disapprove because the young chemist is too valuable to the project.

Evans still shows reluctance, suggesting two more weeks of trials are needed, so Ben angrily pulls rank on him and orders the results submitted. Carlos accidentally falls overboard while clowning around on the boat, and swims into the repellent cloud for protection. He panics and stabs a shark that ventures too close, drawing a pack that kills him despite the repellent. After Carlos funeral, the demoralized Evans rebels when Ben suggests they try an earlier theory about using octopod ink as a repellent.
