This Island Earth (1955)

An influential 1950s sci-fi film directed by Joseph Newman and Jack Arnold, shot in beautiful Technicolor. It's more talky than many genre works from the era, spending much of its time exploring concepts with a central character who's as intrigued by the mystery behind the changing events as we are, namely Dr. Cal Meacham (Rex Reason), a competent pilot, scientist and owner of a handsome voice. While not a typical invasion scenario, amid some neat FX the film nevertheless has the expected alien creature to wow the audience.
If you enjoy the charms of 50s sci-fi and haven't yet seen This Island Earth, it deserves a place on your to-watch list, imo.
