Frankenstein

During production, there was some concern that seven-year-old Marilyn Harris, who played Maria, the little girl thrown into the lake by The Monster, would be overly frightened by the sight of Boris Karloff in costume and make-up when it came time to shoot the scene. When the cast was assembled to travel to the location, Harris ran from her car directly up to Karloff, who was in full make-up and costume, took his hand, and asked "May I drive with you?" Delighted, and in typical Karloff fashion, he responded, "Would you, darling?" She then rode to the location with "The Monster".

According to DVD commentary for this film, director James Whale intended this film to take place in an "alternate universe" and therefore freely mixed 19th Century and 1930s technology, hair fashions, etc.

In the opening credits: The Monster - ?

SPOILERS: The picture was scripted and filmed with Dr. Frankenstein seeming to die in the mill with his creation, but was instead released with a hastily re-shot happy ending, wherein Henry survives to marry Elizabeth (see "Trivia"). However, the sequel, The Bride of Frankenstein (1935) literally followed the first scenario, and consequently just before "Bride" opened this film was reissued with the original finale restored. This movie was seen this way in all subsequent theatrical releases of the old Hollywood era, but when the entire package of classic Universal horror films was made available to television in the 1950s, the prints of the original movie carried the happy ending, and the incompatibility with the opening scene of "Bride..." confused new viewers.

Edited into Boo! (1932)
