The barrel of the police officer's rubber prop gun visibly bends back and forth as he is chasing the Sun Demon on top of the gas tank.
Towards the end of the film in two shots separated by a shot of the monster wrestling with a policeman, two police cars arrive at the gas holder from different directions - they both have the same license plate number (PBU 839).
During a scuffle between George and Gil at Trudy's house, George pulls out a Colt.
45 handgun and forces Gil outside.
But when the scene resumes outside, the gun is now a Luger.
When the doctor is talking about how humans develop in the womb, he places a picture of a cro-magnon man on top of another book showing pictures of "intermediate classes" of animals.
When he removes the picture, however, the book is showing pictures of the developing stages of a human.
When Gil fight the cop on the top of the storage tank he has stains on both the front and the back of his pants.
In the next scene as he runs up the stairs the stain on the front is not there but when he turns to confront the cop it has reappeared.
Robert Clarke wrote, directed and stars in this low budget thriller about a scientist who is hideously transformed after exposure to cosmic radiation. The film plays much better than it really ought to for several reasons.
Though a lot of people might say otherwise, Robert Clarke's cult sci-fi horror/monster movie is actually quite good. With some good performances from the lead characters, even though the explanation behind the monster is ridiculous the film itself is quite entertaining with what seems to be an imaginative spin on the werewolf legend.
The moral of this film is don't drink and do science at the same time! Alas, Gilbert McKenna had to learn this the hard way.
After being exposed to radiation, a scientist (Dr. Gilbert McKenna Robert Clarke)) develops a peculiar form of sun-sensitivity: daylight devolves him into some kind of lizard-man.
If I have this right, Richard Clarke made this movie on his own (starred in it, wrote it, and directed it) after finishing up "The Astounding She-Monster" because he thought he could do better. Well, yes, that turned out to be correct.
Just awful.Has an ok premise but beyond that offers nothing of value or substance.
The Hideous Sun Demon (1959) is a watchable, well-paced and imaginative low budget sci fi effort with an uninspiring script and questionable acting performances.The story for The Hideous Sun Demon was apparently inspired by Robert Louis Stevenson's The Strange Case of Dr Jekyll and Mr Hyde.
I simply cannot believe this movie has such a low rating. I love everything about this movie, from the monster design to the mood and the dark noiresque atmosphere.
Definitely one of the more enjoyable low-budgeted SciFi/horror hybrids of the late 50's, thanks to a combination of interesting plot and characters and – oh yeah – a whole lot of unintentionally hilarious incompetence! The film distinguishes itself from contemporary efforts in two important areas, namely more fast-paced action and less polished lead characters.
