Captain America star Chris Evans believes no other superhero movies can match the ones set in the Marvel Cinematic Universe (MCU).
The actor will return to screens as the title character in Captain America: Civil War, the 13th movie made by Marvel Studios in the MCU.
The star feels Marvel movies, which include those featuring Captain America and other members of the Avengers superhero team, cannot be copied or matched as they keep getting bigger and better.
"Let's keep going, let's let the wave get bigger and bigger, it's not like they're making bad movies, they're making great movies and if you want to put them in this superhero box you can but they're good movies," he told Variety magazine. "They've (Marvel Studios) got a monopoly on it, they're doing it and no one else can try and copy it."
The Marvel films have enjoyed a run of critical and box office success since the first installment in the franchise, Iron Man, hit screens in 2008.
However, they now face competition for comic book fans' loyalties from DC Comics and Warner Bros.' new Justice League series, which will see popular characters including Superman, Batman, and Wonder Woman join forces on screen in a similar way to characters from the MCU.
The second film in that franchise, Batman v Superman: Dawn of Justice opened last month and topped the U.S. and U.K. box office charts despite a barrage of bad reviews.
Despite the new challengers, Marvel Studios boss Kevin Feige still believes his slate of superheroes, which as well as Chris' character includes Chris Hemsworth as Thor, Robert Downey, Jr. as Iron Man and Scarlett Johansson as The Black Widow, are the ones to beat, saying, "There has never been an ensemble like this in cinematic history."
Captain America: Civil War co-director Joe Russo thinks some of the fresh characters fans will see alongside the Avengers for the first time in the new film will help keep their franchise fresh.
“We wanted to bring in characters that didn’t have the same emotional investment that The Avengers had," he says. "Bringing in characters like Spider-Man and Ant-Man, who don’t have that baggage, allowed us to bring new color to the film.”
Moviegoers will get the chance to make their own judgment when Captain America: Civil War is released in the Philippines towards the end of April 2016.
