Attack of the Giant Leeches (1959)

A backwoods game warden and a local doctor discover that giant leeches are responsible for disappearances and deaths in a local swamp, but the local police don't believe them.

Skid-row monster movie is pretty bad, but has some creepy atmosphere and the creatures are hilarious.

Halliwell: "The bottom of the Corman/AIP barrel, good only for a few unintentional laughs."

Maltin*1/2: "Ludicrous hybrid of white trash and monster genres..."

Night of the Blood Beast (1958)

An astronaut is killed on reentry to Earth, but his body is seeded with rapidly gestating aliens.

Absurd low-budget sci-fi tale hardly is worth watching, even for the occasional laugh.

Maltin*1/2: "Well directed but too low budget to succeed."
