"Avengers" franchise alumni Mark Ruffalo and Don Cheadle sat down with "Good Morning America" to talk about the upcoming sequel of the Marvel flagship movie "Avengers: Infinity War" and fans got more than they bargained for. Ruffalo not only “let slip” a major plot point of the movie, he may have revealed the biggest one in recent memory!

Is it true that Superheroes get the wrong end of the stick in Marvel Cinematic Universe?

Mark Ruffalo, the actor who plays that big green barbarian called the Hulk in the MCU’s "Avengers" series, was asked to pour his thoughts regarding his upcoming film, "Thor: Ragnarok." “Let me just say this; Like every other Marvel movie, it doesn’t end well for the superheroes,” Ruffalo said in his usual nonplussed manner.

It would have been fine had Ruffalo stopped right there. After all, there is something to what he said, regarding superheroes getting a bad deal when it comes to the ending of a superhero movie. While anyone could argue that almost all superhero movies end with the heroes triumphing over evil, the typical MCU films carry an emotional weight that allows viewers to emphatically connect with the characters. Had Ruffalo stopped right there, the argument about Ruffalo’s words and its implications to "Avengers: Infinity War" would revolve have around that.

However, Ruffalo couldn’t stop himself. “Wait until you see this next one,” Ruffalo said, referring to "Avengers: Infinity War." “Everybody dies.” This prompted Don Cheadle to censor Ruffalo with a well-timed "Dude!" while shifting uneasily in his seat and looking off-camera seemingly in panic.

Ruffalo visibly blanched. “Not everybody - no. Is that - can we rewind that part?” the Hulk actor asked before adding. “Am I in trouble? Is Barry going to be mad at me?” Cheadle, recognized by Marvel non-hardliners as the guy who uses the other Iron Man suit, told him to move on and forget about the issue.

Fans have got to hand it to these two actors.

Either they really have blundered and revealed a major story arc within the film, and by major, it means killing off the main casts, or Ruffalo and Cheadle are just hyping up a movie that doesn’t need more hype. With all the rumors regarding the fate of Captain America, the seemingly mid-life crisis Iron Man is facing, the character rehabilitation of the Winter Soldier, and the grand debut of the web-slinging hero Spiderman and the eccentric Doctor Strange, maybe Ruffalo's statement is an Easter Egg of some kind and fans have to wait for "Avengers: Infinity War" to break it.

Either way, MCU executives can’t do anything about Mark Ruffalo’s “accidental slip.” Barring a complete rewrite and a complete reshoot of "Avengers: Infinity War", which would be an idiotic way to confirm that Ruffalo is right on the money, Marvel Studio is expected to let this one slip and will probably just use it to hype up their upcoming movies. But one thing is for sure, there isn’t going to be a standalone Hulk movie for the foreseeable future. And it’s not because of Ruffalo’s words.

MCU not doing a Standalone Hulk Movie

The Hulk has a huge following and for casual movie buffs, it doesn’t make sense that Marvel Studios hasn’t taken advantage of the opportunity. However, Ruffalo revealed the real reason why a Hulk standalone movie hasn’t been done by Marvel.

According to the actor, Universal has the rights for a Hulk standalone film and that “they (Universal) don’t know how to play well with Marvel Studios, and they don’t like to make money.”

Fans are going to be treated with an early Hulk appearance this year as Mark Ruffalo joins Chris Hemsworth in "Thor: Ragnarok." The third installment in the "Thor" franchise is set for worldwide release on October 25, 2017.

"Avengers: Infinity War" is set to hit the theaters on April 25, 2018. Joining Ruffalo in the latest film in the "Avengers" Series are Robert Downey, Jr., Chris Evans, Chris Hemsworth, Jeremy Renner, Scarlett Johansson, Tom Holland, Elizabeth Olsen, Paul Bethany, Sebastian Stan, Benedict Cumberbatch, Benedict Wong, Chris Pratt, Zoe Saldana, Karen Gillan, Vin Diesel, Dave Bautista, Bradley Cooper, Pom Klementieff, and Josh Brolin.
