11. A COPYRIGHT LAPSE AIDED THE FILM’S POPULARITY.

Though it didn’t make much of a dent at the box office, It’s a Wonderful Life found a whole new life on television—particularly when its copyright lapsed in 1974, making it available royalty-free to anyone who wanted to show it for the next 20 years. (Which would explain why it was on television all the time during the holiday season.) The free-for-all ended in 1994.
