1. THE MOVIE WAS ORIGINALLY CALLED THE BIG HEART.

According to Turner Classic Movies, it was director George Seaton who lobbied for the name The Big Heart. "I am crazy about the title The Big Heart. If we can clear it, it is a natural," wrote Seaton in a memo to producer William Perlberg. "It is the kind of title like Sentimental Journey[1946] that made such a hit previously with [John Payne and Maureen O'Hara]." It didn't stick with American audiences, but it was first released under that title in the U.K.
