It was very on trend in the 1950s for movies concerning blob-like creatures, with a taste for human flesh. There was The Blob, obvs, The Quatermass Xperiment, X the Unknown, and a whole slew of others, all squelching around, trying to cause as much chaos as inhumanly possible. Spotting the trend, director Riccardo Freda jumped on the amorphous bandwagon, with his sci-fi horror Caltiki, the Immortal Monster.
Originally released in 1971, A Bay of Blood was later refused certification from the BBFC in 1972, ensuring that the film could not be shown at any cinema within the United Kingdom. Fast forward to 1984, and the unmonitored home video market was beginning to find traction with consumers. Bava’s A Bay of Blood would finally find a UK audience upon it’s simultaneous release on VHS and Betamax (from Hokushin under the title Blood Bath) that same year.
