Warner Bros. felt the wrath of Deadpool as star Ryan Reynolds stood up to them on Twitter. The actor responded to a tweet.

The Real Merc With A Mouth

Reynolds had the ideal response when the studio behind his superhero flop Green Lantern tried to shame him for taking a shot at the 2011 flick in his lampooning meta-superhero movie Deadpool 2, which is in theaters now.

"We're going to need that ring back," the studio's Twitter account wrote on Saturday, calling the former Hal Jordan out for his lack of respect.

The studio was referring to his Green Lantern ring, which gives Jordan his powers. Never one to back down from an online war of words, Reynolds responded with a reference of his own.

"Well, if we'd used a NuvaRingTM️ in the first place, we wouldn't be in this mess," Reynolds replied, referencing the well-known vaginal contraceptive ring popular at the time of the movie's release.

It Was A No-Brainer

Reynolds infamously abandoned Warner Bros' planned DC cinematic universe to launch Marvel's Deadpool franchise, his pet project throughout his entire career.

Deadpool, although it's only two movies in, has already been a considerable hit for 20th Century Fox, which is now owned by Disney. Deadpool 2 just knocked Avengers: Infinity War off the No. 1 spot at the box office, with universally positive reviews across the board.

At the time of writing, the flick has an 83 percent score on Rotten Tomatoes, versus Green Lantern's dismal 26 percent. Likewise, Deadpool grossed over $783 million worldwide off a $58 million budget. To date, the sequel already netting $301 million worldwide. Green Lantern grossed just $219.8 million off a $200 million budget.

Reynolds has appeared in several comic book movies over the years, including Blade Trinity, RIPD, and X-Men Origins: Wolverine. Deadpool was his first commercial and critical success.

The Green Lantern Lives

He starred as Jordan, who becomes the titular hero, in 2011's Green Lantern, which the studio deemed to be enough of a hit to have a sequel. It never happened.

Jordan gets his powers via a ring bestowed on him by powerful aliens, hence Warner Bros' tweet to Reynolds. Both Deadpool movies have referenced the flick in an unflattering light. The star, for his part, appears to be suggesting the film shouldn't have been conceived at all.

The studio clearly doesn't agree. It is developing a new Green Lantern movie, Green Lantern Corps, aimed for a 2020 release. Early reports suggest two Lanterns will feature as co-leads, with a buddy cop dynamic, not dissimilar to the one Reynolds shared with Jeff Bridges in RIPD.
