That's right -- if you haven't guessed it already, Ryan Reynolds is enlisting the help of beloved child actor and "Super Troopers 2" star, Fred Savage, to reprise his role as "the kid being read to" in "The Princess Bride."
Only this time, Deadpool is the grandpa.
But the fun doesn't stop there! The fun stops when you regret bringing the kids to the movies in the first place, but hey -- a PG-13 version of Deadpool is pretty awesome if you ask us.
Check out the trailer below and remember to be extra naughty this year, because that's what Deadpool would want.
"Once Upon A Deadpool" is in theaters on Dec. 12.
