Truly successful exploitation flicks don’t have a ton of plot, and “Mad Doctor Of Blood Island” is chock-full of scenes that have only the most tenuous connection.
Such as they all happen on the same island.
The movie does have some of the best gibberish chanting music I’ve encountered this side of a good Satan movie.
There’s a native dance sequence that owes more to Burbank than Borneo, but hey, a girl in a grass skirt is a girl in a grass skirt.
The in-shot zoom, very popular in the 1960s, is employed to great if slightly nauseating effect here, with incessant and rapid zooming used about as often as scary music.
Fuzzy and/or green zombies, nekkid girls running through the jungle, a green blood cult and the best in late 1960s leisure wear.
Even the dubbing is competent.
So settle in for an excellent 90 minutes of cheesy goodness.
