This was the only film in which Gene Lockhart appeared with his wife Kathleen Lockhart and their daughter June Lockhart.
MGM released a record-breaking 375 prints of the film so that as many people as possible could see it during the Christmas season.
The word "humbug" is misunderstood by many, which is a pity since the word provides a key insight into Scrooge's hatred of Christmas. "Humbug" describes deceitful efforts to fool people by pretending to a fake loftiness or false sincerity. So when Scrooge calls Christmas a humbug, he is claiming that people only pretend to charity and kindness in a scoundrel effort to delude him, each other, and themselves. In Scrooge's eyes, he is the one man honest enough to admit that no one really cares about anyone else, so for him, every wish for a Merry Christmas is one more deceitful effort to fool him and take advantage of him. This is a man who has turned to profit because he honestly believes everyone else will someday betray him or abandon him the moment he trusts them.
