Beyond Atlantis is a 1973 American-Filipino science fiction horror film directed by Eddie Romero, written by Charles Johnson, based on a story by Stephanie Rothman, and starring Patrick Wayne and John Ashley.

Back on the mainland, the fisherman Manuel the Barracuda (Vic Díaz) pays East Eddie (Sid Haig), who runs the piers, with some pearls.

Nereus decides that the group must die, and Vic, Logan, Eddie and the crew have to fight their way back to their boat.

[6] The budget, variously estimated at $200,000[7] or $250,000,[8] was higher than usual for movies shot in the Philippines at the time due to the use of underwater photography.

Producer John Ashley admitted that the movie was meant to be a ripoff of The Treasure of the Sierra Madre, but he had high hopes for it because he liked the script so much.

"[9] Ashley said that the original intention was for the lead characters to discover the people living underwater, and "for the most part they were going to be topless".

[9] However Larry Woolner, the head of Dimension Pictures, thought that they had the chance to make a slightly more ambitious film.
