Saucer-Men, Screaming Skulls and Gila Monsters at R-S-R!

THE GIANT GILA MONSTER (1959): http://radiation-scarred-reviews.blogspot.com/2009/12/giant-gila-monster-1959.html
"Incidentally, the Giant Gila Monster is portrayed not by an actual Gila Monster, but by the closely-related Heloderma horridus horridus, the Mexican Beaded Lizard. Similar in appearance, the Mexican Beaded Lizard has duller coloration and a longer tail. I guess THE GIANT MEXICAN BEADED LIZARD just isn't as catchy a title."

THE SCREAMING SKULL (1958): http://radiation-scarred-reviews.blogspot.com/2009/12/screaming-skull-1958.html
"Despite lacking lungs, a diaphragm, lips, tongue, and palate, that skull sure does scream a lot. Except that it doesn't. At all. The skull is impressively silent, since it is, in fact, a disembodied skull with a wired-on jaw bone."

INVASION OF THE SAUCER-MEN (1957): http://radiation-scarred-reviews.blogspot.com/2009/12/invasion-of-saucer-men-1957.html
"A flying saucer lands outside of town, being spotted by a couple teenagers and Joe Gruen, a drunken con-man (played by Frank Gorshin, who went on to fame playing the Riddler opposite Adam West's Batman). The Air Force is soon on the case, but not before teenage sweethearts Johnny and Joan run over a Red Planet Pedestrian with Johnny's roadster."
