IMDb page for the movie Milk:
Errors made by characters (possibly deliberate errors by the filmmakers): In the beginning, as Harvey Milk begins to record his message, a screen card reads “1978.” Harvey says, “Friday, November 18.” November 18, 1978 was a Saturday.
I think I’ve been using IMDb for about fifteen years now. (Remember when there wasn’t an Internet? Crazy, right?) If I’ve learned anything from IMDb’s goofs section, it’s that there is someone somewhere who watches every single movie and makes sure the dates and days of the week match up. What a bizarre hobby that must be. I imagine this person–let’s call him Rick–has the days of the week in history algorithms memorized. When somebody in a movie says, “And then I killed him on Saturday, July 14, 1963,” Rick completely freaks out.
