So, they’re doing a PG-13 version of Deadpool 2.

No, really.  Limited theatrical release (December 12-24), they shot something like eight new scenes, did the whole thing it as a sendup of The Princess Bridethey’re donating part of the proceeds to charity, they kidnapped Fred Savage, and then did the whole thing up as Once Upon a Deadpool.  Calling this a ‘gimmick film’ seems a bit harsh; they’re really working at milking the joke, here.
