Why this one is worth it
This trailer was made to be reacted to
A drama trailer sells restraint, and the reaction it earns is usually just as quiet. Record it anyway.
Theatrical releases are won in the weeks before opening night, and trailer reactions are where that energy starts. Yours can be part of it.
