The restaurant, at which the family eats, was, at one time, a real restaurant; a national chain diner called "Sambo's". It was located directly across the street from Southgate Shopping Center, as it appears in the movie. Due to the controversial nature of the name and interior design, the diner (and entire chain) closed sometime in the late 70s or early 80s, except for the original location in Santa Barbara, California, which, to this day, remains open in its original location. It remained an abandoned building for many years, until Tim Burton came to town to film this movie. Burton's crew unboarded the doors and windows and redressed the interior to look like a working restaurant again.
Tim Burton had asked Robert Smith of The Cure to do the soundtrack, and had even sent the script. Robert was busy recording "Disintegration" at the time, and didn't know who Burton was, so passed up the opportunity, handing Danny Elfman the job.
When Edward goes to have his hands sharpened, the storefront was that of an actual hardware store called Crowder Brothers in the Southgate Shopping Center. At the time of the filming, they did offer a sharpening service, and they did have a giant motorized Wenger in the window.
Winona Ryder starred in three films in 1990. "Edward Scissorhands" and "Mermaids", which were released on the same day, December 14, 1990. Ryder was also the star of "Welcome Home, Roxy Carmichael" which was released two months earlier.
During the scene where Edward is cutting the neighborhood ladies hair, the song playing is from Sweeney Todd: The Demon Barber of Fleet Street. Johnny Depp would later go on to play Sweeney Todd in another collaboration with Tim Burton.
