Niagara Falls is a 1941 American comedy film directed by Gordon Douglas and starring Marjorie Woodworth, Tom Brown and ZaSu Pitts.

A peanut vendor sights a man named Sam Sawyer attempting suicide by jumping off a cliff into the waters below.

As the two are not keen on the idea, Sam marches them at gunpoint into the smaller room he and Emily had taken in exchange for the bridal suite, and locks them in.

To the distress of Emily, Sam is so keen on bringing the couple together he stays up all night with his large revolver facing their room to prevent escape attempts.

ZaSu Pitts and Slim Summerville had made a streamliner prequel Miss Polly playing the same characters.
