The Impossibly Difficult Name that Movie Game

What does a group of adults do when they gather together during the winter? Act like children and have a snowball fight, of course! If you can guess the film this screenshot is from then your brains obviously have not been frozen by Old Man Winter's frosty breath yet. 

As usual, if you are not familiar with the rules to the Impossibly Difficult Name that Movie game or the prize, click here.

Good luck guessing! 

GAME OVER. 

Congratulations to The Tactful Typist for correctly guessing "H.M Pulham Esq" ( 1941 ). In this scene Ruth Hussey just got whacked with a snowball thrown by Robert Young.
