Movie Facts 'It's a wonderful life'

1. Jimmy Stewart didn't like the script at first

After laying out the plot line of the film for Stewart in a meeting, Capra realized that, “This really doesn’t sound so good, does it?” Stewart recalled in an interview. Stewart’s reply? “Frank: If you want me to be in a picture about a guy that wants to kill himself and an angel comes down named Clarence who can’t swim and I save him, when do we start?”

2. The movie wasn't a hit at the box office

Though it has become a quintessential American classic, It’s a Wonderful Life was not an immediate hit with audiences. In fact, it put Capra $525,000 in the hole, which left him scrambling to finance his production company’s next picture, State of the Union.

3. The Rock that broke the window was real

4. The film was shot during a heat wave

It may be an iconic Christmas movie, but It’s a Wonderful Life was actually shot in the summer of 1946—in the midst of a heat wave, no less. At one point, Capra had to shut filming down for a day because of the sky-high temperatures—which also explains why Stewart is clearly sweating in key moments of the film

5. Zuzu didn't see the film till 1980

Karolyn Grimes, who played Zuzu in the film, didn’t see the film until 1980. “I never took the time to see the movie,” she told Detroit’s WWJ in 2013. “I never just sat down and watched the film.”
