The Giant Claw (1957) horror monster science fiction movie.
I found this movie's special effects to be ridiculous and pathetic, but I couldn't quit watching! Global panic ensues when it is revealed that a mysterious UFO is actually a giant bird that flies at supersonic speed and has no regard for life or architecture. From Wikipedia: The Giant Claw (a.k.a. The Mark of the Claw) is a 1957 American horror monster science fiction film from Columbia Pictures, produced by Sam Katzman, directed by Fred F. Sears, that stars Jeff Morrow and Mara Corday. Both Sears and Katzman were well known as low-budget B film genre filmmakers. The film was released as a double feature with The Night the World Exploded.
