Every mega-successful Hollywood blockbuster is inevitably followed by a flood of knock offs and Star Wars was no exception. It started with Battlestar Galactica. I was lucky to see the movie version and I loved it every minute of it. I didn't know or care that it was in reality a few TV episodes thrown together to exploit a crazed market eager to throw its cash at anything that even vaguely resembled Star Wars. And it was in "Cine-Fi" sound.

On the back of the clipping - Marcia, Grease and the Shaft 'Sinema.' Yep, it's the 1970s alright.
