It's 20th Century Fox's first day at school under new headmaster Disney.

The Mouse House will officially acquire the iconic studios at the very specific time of 12:02 a.m. ET on March 20.

And Deadpool is heralding that with his first school picture.

The Merc With a Mouth, aka Ryan Reynolds, posted the below picture on Twitter with the line: "Feels like the first day of 'Pool."

The unconventional Marvel superhero, whose home at Fox saw two R-rated films as well as a PG-rated version of Deadpool 2, seems remarkably chipper under his new clean-as-a-whistle corporate overlords, and that's probably because Disney has a history of allowing the companies it owns to produce R-rated films. Shortly after Miramax was acquired by Disney in the '90s, the Bob and Harvey Weinstein-founded company came out with the R-rated Pulp Fiction.

Disney CEO Bob Iger reportedly addressed Deadpool's situation in a conference call with investors at the end of 2017 when the news of the acquisition broke, saying there would be an "opportunity for an R-rated Marvel brand as long as we let audiences know what's coming."

The merger also moves Deadpool's X-Men superhero-mates into the new digs, along with the Kingsman and Planet of the Apes franchises.

That's $71.3 billion well spent.
