It doesn't matter if Wolverine has never appeared in an R-rated movie: Hugh Jackman really insisted that Logan—his finale playing the X-Men favorite—get the big Restricted tag. The news comes from Ain't It Cool News' Eric Vespe, who was at the website's 18th annual Butt-Numb-A-Thon 24-hour film marathon in Austin, Texas. Director James Mangold, returning from 2013's The Wolverine standalone, screened the first 40 minutes of Logan, and spoke:

Could Jackman have really taken a big enough pay cut to make a difference? Studios are notoriously R-phobic with superhero movies, which is what made Deadpool's success so notable earlier this year. Screenrant reminds us that the Ryan Reynolds–starring flick was the first R in the X-Men universe; none of the six core films have ever been anything but PG-13. Ditto for The Wolverine and its predecessor, 2009's X-Men Origins: Wolverine. 

Deadpool's $363 million makes it the No. 5 domestic earner of 2016 so far, and the sole R-rated flick in the top 10. X-Men: Apocalypse is down at No. 13 with $155.4 million.

Logan drops March 3, 2017. Watch the trailer here, and see the stars of X-Men: Apocalypse tell us their favorite mutant powers below:
