And there's nothing at all in the trailer which tells audiences that they'll be seeing a musical instead of a straight remake of the movie.
I saw a different trailer in theaters with no knowledge this movie was even happening, and seeing clips of group dance numbers immediately clued me in to "oh my god they're remaking it and it's a musical now".
Granted this was probably made for the Taylor Swift thing and they went "what the hell, put it in front of Five Nights at Freddy's too".
Very odd that they'd pull back from the musical stuff for the final trailer.
