"Infinity War" crashes into theaters on May 4th. It's the third "Avengers" movie (if you don't nerdily count "Captain America: Civil War") . . . and the 19th movie since Marvel launched the series with "Iron Man" in 2008. The fourth "Avengers" movie is coming out in 2019.
It's possible that not all the characters will make it out of these next two "Avengers" movies alive. Marvel Studios boss Kevin Feige recently said these movies will be a turning point.
Quote, "We've got another 20 movies on the docket that are completely different from anything that's come before . . . there will be two distinct periods. Everything before ['Avengers 4'] and everything after."
