A group of people wake up to find their city deserted due to an invasion of alien robots from Venus. While the military tries to figure out a way to fight back, these people hole themselves up in a hotel where they are safe. That is, until a psychopath shows up! After an impressive start, it drags some as they sit around the hotel room scared of the robots outside. The cast is decent, with stars like Richard Denning and Virginia Grey leading the way. Both were somewhat successful but should’ve been bigger than they were in their respective careers. Beautiful Kathleen Crowley and character actors Richard Reeves, Arthur Space, and Whit Bissell are also good. Robert Roark, however, is another story. According to the trivia section here on IMDb, he got this part because his father would only invest in the film if they cast him. I can believe that as he’s the weakest part of the cast and seems to be imitating characters he saw in other movies.

The interactions between the group are pretty clichéd and cheesy but somehow I couldn’t help but like them (except Roark) due to the charisma of the actors. It’s kind of funny to watch Denning deduce the invaders are from Venus because of stuff he learned from reading his friend’s sci-fi magazines in college. The inevitable romance between he and Crowley comes on super fast, with them falling for each other hard within hours of meeting. This is made all the more implausible when you see how much of a jerk he is to her in the first part of the film.

As others have pointed out, the special effects are limited. There’s one rather silly-looking robot that they keep filming yet they tell us there’s supposed to be a whole army. Look, ’50s sci-fi was the best but sometimes its charm was in its goofiness. The robot here is pretty goofy. The actual invasion stuff takes place off-screen and stock footage is used a little too much. Still, despite its shortcomings, it’s an entertaining movie.
