poor projectionist...
I'll tell ya....I've been a projectionist for 30 years....
and this was one of the toughest ones to correctly show.
It was very hard to concentrate on the reel change-over
as the drive-in projectionist gets shot right at the actual the reel change.
I always thought it'd be fun to let the film runout at that point
and just slump over one of the projectors. :)
( Another tough one was "The Harder They Come" ...
where the change-over happens as a guys face gets sliced up with a knife)
