Tulips Shall Grow (1942)

Although uncredited at the time, Tulips is Ray Harryhausen's first commercial work as chief animator. It’s set in what appears to be Holland. In a beautiful village with idyllic windmills, a pair of lovers, Jan and Janette, fear for their lives when an invading military force known as The Screwballs move in.
The aggressors resemblance to Nazi soldiers is certainly no coincidence, given that Dir. George Pal had previously lived in Holland and, furthermore, left his home (in Prague) to escape their rise to power.
The simple animation gets more adventurous and complicated as the danger level increases, but thanks to Harryhausen it's always astonishing.
