BTS

BTS

An initialism of "behind the scenes," used as a modifier to describe something that occurs during the making of something, especially a film. We've hired a separate film crew to document the entire BTS production process. Shocking new BTS footage shows the actor exploding at the crew with a torrent of profanities.
