20 Things You Didn't Know About It's A Wonderful Life
3. Christmas In Summer
Speaking of snow, you probably noticed how much of It’s A Wonderful Life takes place during the winter season, from Harry Bailey almost drowning in the frozen lake to George Bailey running happily through a snowy Bedford Falls.
But you probably couldn’t tell that most of the movie was filmed during a heat wave in July. Perhaps the one give away is how George Bailey is sweating profusely in the snowy evening scenes.

It got so hot that Frank Capra allowed a day off for cast and crew in order to convalesce.
