I had never encountered the film before, but I'm certainly glad I have now!
It isn't really the plot that will keep you coming back to this, but the non stop barrage of pop references and comic book editing that made me think of Lucky The Inscrutable with lots more nudity and less budget in a great way. It never stops! Here is a look at not only Richard Corben's DEN appearing, but also the amazing poster for Nosferatu featuring Franco's old collaborator, Klaus Kinski.
I almost fell out of my chair! Den makes a few other appearances as well. Also, you have to love a dancing thug! This scene is cool in that it takes the tried and true beatdown and has Analia Ivars (in her first Franco role) in there to boot. Watch for Dancing DoBadder to unleash a stomping!
And you can really get a feel for the editing as Jess Franco makes his first appearance right here!
And it does not pay to beat up Antonio Mayans when he is named after Franco's smokes... I love that he keeps on dancin' till the end.
I think my revelation in this film was two fold. I owe Franco a big debt in the appreciation that hunting for his movies for the last 20 plus years has allowed me to enjoy cinema on a purely visual level, almost freed from the chains of plot and the sometimes less than logical scripting of exploitation cinema worldwide. While I know that I miss many cultural references in his films, I also learned to forget fearing that and begin to underthink the story and truly enjoy the visuals. Los blues de la calle Pop is perfect for this!
