Nocturna, Granddaughter of Dracula!
This is my next must-find, and after watching the two clips below you’ll no doubt understand why once I locate it, I’m adding Nocturna to the screening list for Price Chompers Bushwick Discount Uniplex Pavilion.
Nocturna is a 1979 disco vampire movie starring the late, great Lily Munster - Yvonne DeCarlo in the titular role and featuring disco numbers by Gloria Gaynor, Vickie Sue Robinson, Anthony Hamilton, and Moment of Truth.
Here’s the opening sequence:
And a later sequence where Nocturna learns to dance. Keep watching till the end - it’s worth it.
His band must be pretty good - he can walk away from the guitar in the middle of a number and it keeps playing!
