Character mistake: When Sheriff Brackett is talking to Loomis at the food stand, he calls him Don. His name is Sam. Even says it in the subtitles. (01:19:35)
Suggested correction: He could possibly be saying "Doc".
No, he's definitely saying "Don." It's never been addressed, but I think it's an honest mistake with two people who have never met before and maybe an homage to Donald Pleasance, who played Loomis before.
It's hard to say, but it does sound like "Don." The sheriff says "doc" two times later in the same scene and those two times definitely sounds different than the first time. But I don't think it's meant to be a homage to anyone. I think it's just an actor who flubbed the word.
Character mistake: The title card shown after Deborah's suicide states that Michael's escape from the asylum takes place "Fifteen Years Later." Yet the night after the escape, Sheriff Brackett refers to her suicide having been seventeen years ago. (00:38:40 - 01:29:00)
