Speaking of Fred Savage and The Princess Bride, the Once Upon a Deadpool idea was originally pitched to Ryan Reynolds by a fan on Twitter last December, before Deadpool 2 even came out.
Once Upon a Deadpool will feature 20 minutes of brand-new footage, according to Deadpool 2 actor Julian Dennison in a new promo.
Ryan Reynolds and crew assembled a small crew to film the additional scenes included in Once Upon a Deadpool.
Reynolds and Savage have a good chemistry together that is evident after watching the first Once Upon a Deadpool trailer.
