Matrimony's Speed Limit

Ignore the previous comment - the Keaton film was much later.

A man does badly on Wall Street but refuses to borrow or take money from the woman he is engaged to, so she sends him a message seemingly from a law firm stating that his aunt has died but he must be married by 12 noon that day to be eligible to inherit her money. He makes several comic attempts to marry women who are at hand before marrying the lady who sent the letter just before noon.

Nice shots of suburban Fort Lee, NJ.
