Plot Hole That Takes Down The Movie In Opening 30 Seconds
Ok, so it's "just a movie", I get that but let's just for a second assume there is an OUNCE of realism attached to it - what school (either in the 1970s or modern day) uses a REAL drop-door gallows and noose?!
The entire set looked garbage: all painted backdrops and paper mache and bits of wood nailed together like your typical high school production with a prop budget of $3.40 - except of course for the gallows.
No one in their right mind in lawsuit America would use a real noose and real doortrap gallows for some crappy amateur school play. (I know, that might be taking things a bit too realistically, but come on; all it takes is some teacher to say "we'll use pretend gallows in case someone gets hurt and the school gets sued for $40m" and the entire movie never ever happens. Or its sequel. Or prequel.)
