Raiders From Beneath The Sea
A plot to rob the Catalina Island bank with scuba gear.
This remotely suggests The Snorkel (dir. Guy Green) and in another way Murph the Surf (dir. Marvin J. Chomsky).
The mainland locations are similarly viewed in Welles’ Touch of Evil and Polanski’s Chinatown.
The anticipation of Edward Albee’s Seascape in Avalon is rather striking.
“You try and score on a bank, that’s just plain war.”
TV Guide, “average caper film”.
