So Glad I finally caught this on the DVD double bill with Creation Of The Humanoids . I saw the trailer for this at a grindhouse in the seventies after the release of Star Wars. Obviously some cheap distributor dusted it off the shelf and reissued it with a Star Wars like title to pair up with another sci-fi. I remember the audience howling at the preview especially when the astronuts start hacking up the a.liens which are nothing more than plastic tubes filled with strawberry Jello. Ever since I've been trying to find it. As Space operas go it's not the best and it's not the worst. It's certainly a time capsule of everything sixties .AnTonio Marghetti seemed to be the go to guy for these psychedelic mash ups of James Bond and George Jetson starting in 1960 with Space Men and ending in the early seventies(I think) with The SNow Devils AKA The Blue Devils. My favorite in the series is Wild Wild Planet with it's four armed assassins and biosphere of blood. Most of these would grace the late night air waves when the insomniacs and users of contraband were up and wanting something different. If you like em cheap and Campy you could do worse, As for really boring cinema try The Dead Talk,The Incredible Petrified World, Treasure Of El Cortez, Or That Man From Harlem.
