Pino Donnagio - Hercules (1983) and The Barbarians (1987)
For today's peplum entry I'll supply a double shot of Pino Donnagio, who delivered some fantastic synth-heavy scores for the films 'Hercules' and 'The Barbarians'. The former stars Lou Ferrigno of 'Incredible Hulk' fame and the latter stars Peter and David Paul, the bodybuilding twin brothers famously known as "The Barbarian Brothers".
I've seen neither movies, nor do to own the soundtracks (though I'm always on the lookout for a reasonably priced CD copy).
The Barbarians - Main Titles
The Barbarian Brothers were featured in a deleted scene for the 1994 film 'Natural Born Killers' in which they played "The Hun Brothers." Amusing.
