'Captain America' leads biggest fight in Marvel history

His view is echoed by Anthony Mackie, who stars as Falcon, the only superhero who can fly in Captain American's team.

"As the audience, you can choose which side you want to support. Everyone can relate to it (the movie)," says the 37-year-old American actor.

He says the brotherhood between his character and Captain America can be compared to that between Romeo and Mercutio, as depicted in William Shakespeare's Romeo and Juliet.

For Chinese audiences, who have been exposed to Marvel comics for only a few years now, they could be confused about the complex relationships and names in the movie, as every character has his or her real name plus a superhero title.

Some Beijing moviegoers reached by China Daily say it is a problem to remember all the faces in Marvel's previous big-cast movies such as the Avengers franchise. But they are all impressed by the movie's stunning chases and fights.

Despite Avengers: Age of Ultron raking in 1.46 billion yuan ($231 million) in China last year, the movie was far behind the Chinese champion, Monster Hunt, which grossed 2.44 billion yuan in 2015.

Meanwhile, compared with Marvel's decadeslong rival DC Comics, which recently released Batman v Superman: Dawn of Justice, Captain America appears to be a more audience-friendly title, as some critics who saw the previews say on popular movie sites such as Douban.com.

Captain America also exudes quiet confidence when speaking about the film.

"The movie is good, dynamic and entertaining," Evans says in an interview with China Daily.

The superheroes also show their interest in shooting in China.

"It's not only a big market for Marvel, it is also a very important one for me, personally," says Evans.
