Will Hunter be in the movie?

Technically yes, but his name won't be said out loud. By the end of the movie, Buzz will earn the moniker Hunter.

Will this be a remake of the old ROBLOX roleplay?

The old roleplay exists in a separate universe called the PSCU, the movie exists in the Gmod RpVerse. There will be some small details that will call back to the old rp. But other than that, no, this is entirely different, and you'll see what I mean when it comes out in June.

How accurate will this be to the TAOR/Old Bloodtime games?

If you mean character design, then this will include probably the most accurate versions of the characters yet.

If you mean story, then no. It barely has any ties to the games. The only thing taken from the old games was Buzz turning into Hunter, and that's about it. Also, the Cambell family doesn't exist in the RpVerse, and most of the characters from TAOR (with the exception of Hunter) won't be added to it

When will this movie take place and how many nights will there be?

Same as the roblox rp, 2007 (but not 2008). There will also 5 nights, not 6, 7, or 15 like in the ROBLOX Roleplay.
