‘Deadpool 2’ being re-released in a PG-13 version starring Fred Savage

And here Aquaman thought he would have the live-action superhero screen all to himself this Christmas.

On Friday, Ryan Reynolds tweeted out a poster for Fox’s “Once Upon a Deadpool” – a release that represents both a noble act of charity and a brilliant bit of box-office marketing.

“Once Upon a Deadpool” is a recut version of the R-rated summer sequel that tones down the language and violence to se- cure a PG-13 rating. Or as Reynolds tweets of the new version: “The only F word in this movie is Fred Aaron Savage.” And on Instagram, he calls it “a fairy tale that gives zero F’s.” In the poster, Reynolds is pictured clinging to Savage while mounted on a reindeer.

The “Deadpool” franchise, so laced with 1980s references, stays true to such riffing here. Savage played the grandson being read the storybook tale in 1987′s “The Princess Bride”; in “Once Upon a Deadpool’s” new scenes, Reynolds will reportedly read his “Deadpool” adventure to the adult Savage in the same childhood bed.

“Deadpool 2” grossed $734 million worldwide this summer – nearly as much as the first film made in 2016. As Deadline reported this week, Fox had long sought a PG-13 version of a Deadpool film.

“Fox has been asking for a PG-13 basically since the start in 2006,” Reynolds said on Monday. “I’ve said ‘no’ since 2006. This one time, I said ‘yes.’”
