It's lovely Ann Sheridan - who started her movie career by winning a beauty contest - getting a well-deserved onscreen spanking in "The Footloose Heiress", a fast-paced comedy with a playtime of less than one hour.
I had the clip of the spankinhg on my drive, but also was able to locate the original movie trailer for this.
I took both and created a pretty good (I think) combination of both for your maximum entertainment.
The trailer showed the spanking too, but filmed from a different perspective! These shots then didn't make it into the final cut, so they might be new to you.
Here's the clip:
And Miss Sheridan was victim to another public spanking - probably by director John Ford.
Here's the picture (which I've edited to remove the nasty watermark that was all over it originally):
And another nice trivia fact from the IMDB about Miss Sheridan:
In 1939 a fraternity bet inspired a UCLA student to handcuff himself to Ann during a movie premiere and then swallow the key. A locksmith had to be summoned to the theater to unlock her.
Interesting tagline at the end: 'It's Love on the Bum' - I'm wondering if that is a pun or would bum not be known as slang for buttocks in USA?
