Factual error: A poster promoting the July 4th fireworks spectacle includes an illustration of two American flags - each with 50 stars, rather than the 48 stars which they should have at the time. (00:46:40)
Other mistake: In the opening credits, there is one credit that reads "Miss Winter's costumes by Gene Coffin." This is meant to be referring to actress Shelley Winters and the man who provided her costumes, however the apostrophe has been put in the wrong place. Since her full surname is Winters, putting the apostrophe in between the R and S in incorrect. The apostrophe should have gone after the S to spell out "Miss Winters' costumes" and not Winter's.
