I love SI. Also love Ed Hunt's Bloody Birthday too!
Starship Invasions is campy fun! I used to see this on TV all the time in the 80's. I just watched my old Warner Bros. VHS the other night. I wonder how seeing this in the 70's must've been like. If you look real hard you can see Helen Shaver look right at the camera a few times. The redhead Christopher Lee beams down is pretty hot. Robert Vaughn is so serious! I'd like to take some of those space vitamins too to keep up my strength.
This was directed by Ed Hunt who also directed Bloody Birthday about killer children and the creepy UFO's Are Real documentary. I'm not sure if I saw any more of his work.
