Box Office: 'Once Upon a Deadpool' Opens to $1M on Wednesday

The PG-13 version of 'Deadpool 2' hopes to take part in the holiday mayhem at the multiplex.

20th Century Fox's holiday entry Once Upon a Deadpool opened to an estimated $1 million from 1,566 theaters on Wednesday, putting it in a close race with The Grinch for No. 1.

Predicting how much the PG-13 version of Deadpool 2 will make this weekend is tough, since it is an unusual proposition to recut a popular superhero pic. The hope is that the kid-friendly version will lure new fans, although rereleases aren't generally huge earners.

The film will have plenty of competition. On Friday, Spider-Man: Into the Spider-Verse opens alongside Mortal Engines and The Mule. Spider-Verse is expected to win the frame with roughly $35 million.

This summer, the R-rated Deadpool 2 grossed $734.2 million at the worldwide box office, including $318.5 million in North America. In the rejiggered version, Deadpool (Ryan Reynolds) sits at the bedside of Fred Savage — who is reenacting his role in The Princess Bride — and reads to him from the "King James Edition" of a Deadpool storybook.

Earlier this week, Reynolds and Fox announced that one dollar of every ticket sold for Once Upon a Deadpool in the U.S. through Dec. 24 will be donated to Fuck Cancer, which recently changed the foundation's name to Fudge Cancer to be more PG-13-friendly, like the film.
