Verdadeiramente trivial , mas isso aconteceu em Cantando na Chuva (1952) ...
The movie begins with the premiere of Don Lockwood's latest picture, "The Royal Rascal", a silent black-and-white adventure film. The footage shown from "The Royal Rascal" is actually from a film MGM released in 1948, The Three Musketeers (1948), starring Gene Kelly - which is in color and has sound. For this film both color and sound were taken out of the footage and title cards were added. The other change was adding shots of Jean Hagen (who played diva Lina Lamont) in place of "The Three Musketeers" leading lady, Lana Turner. If you look closely, it is Lana--not Jean--opening the door when the spear hits it. The ending of "The Royal Rascal" was shot on the same set used for "The Three Musketeers".
