According to page 70 of "Notes For A Memoir", Janet Jeppson, second wife of Isaac Asimov, describes how she was acting as an extra in this movie on August 14, 1945, when Wallace Beery came out of his trailer to tell everyone on site that World War II had been declared over.
It's interesting to see a wedding ring on Wallace Beery's left ring finger. He was divorced from his second wife in 1939
and his character in this film is not married.
"Lux Radio Theater" broadcast a 60 minute radio adaptation of the movie on
March 1, 1948 with Wallace Beery and Margaret O'Brien reprising their film roles.
