I love movies, that blend multiple genres. I get even more interested if one of those genres is a musical. Still, the more chances you take the more you risk endingĀ  up with something like the genuinely godawful trailer for an insane looking mishmash called “El Dorado” over at Bloody Disgusting, which in this instance is way more disgusting in an aesthetic sense than it is bloody in a literal sense.

It’s so bad in an non-entertaining way and kind of depressing way that I can’t bring myself to inflict it on you here, despite a cast that seems to promise something genuinely unusual. That includes the final appearance of David Carradine, who surely deserved better — but then deserving better in late career films is certainly following in the footsteps of his legendary dad. Still, you can heck out the horror-musical Blues Brother tribute or whatever it is over at Mr. Disgusting’s place if you’re in the mood for a cinematic train wreck, and we all have that impulse.

Instead, I am presenting a couple of minutes sheer insanity that is actually entertaining. Ladies and gentlemen, if you think you’ve seen everything in grindhouse-era movie madness, see this and be amazed and amused. The great Bernie Casey IS “Dr. Black and Mr. Hyde.” (NSFW in a red-bandy, partial frontal nudity kind of a way.)

You’ve got to wonder what Robert Louis Stevenson would have made of that.
