"Avengers: Endgame" is officially opened at movie theaters across the country. It’s the most highly-anticipated movie event of the year and is expected to set a new box office record. Iron Man, Captain America, Black Widow, and the whole Avengers crew are back to do battle with super villain Thanos after he wiped away half of the universe’s population with a single snap of his fingers in last year’s "Avengers: Infinity War." The movie is the culmination of a groundbreaking superhero movie franchise that’s pushed out 22 films in 11 years, starting with the blockbuster "Iron Man" in 2008. With this movie, the so-called Marvel Cinematic Universe is expected to easily bring in more than $20 billion in global box office earnings. Love it or hate it, this franchise has become one of the most ambitious commercial endeavors in the history of Hollywood. This week on Money Talking, Charlie Herman talks to Adam B. Vary, senior film reporter at BuzzFeed News, and Hunter Harris, associate editor at New York Magazine’s Vulture, about how the Marvel universe has changed the movie business.
