Linda Miller stars in this little known gem of movie making, Helen of Troy Goes to Planet X, made 1957. The first movie in the series was The Kiss of Helen of Troy. It more or less followed the Trojan wars until she was teleported away at the end. There is another movie after Planet X called Helen of Troy and the Cannibalistic Cat-People, but it wasn't as good as Planet X.
Synopsis: Following her mysterious teleportation from ancient Greece, Helen of Troy is thrust into a bloody conflict between the Gigakings of Mizar Eta and the Daxstraya on the strange world of Planet X!
