The Marvel movies have been successfully marketed in America and outside of it. A staple of these movies has been Captain America, who is clearly a United States centric character. How has Disney (the company behind these movies) marketed a US centric superhero to a non-US audience?
"From the creators of Iron Man", that's how. Iron Man was super popular. So are superhero films. Even if the comics themselves are pretty niche here (like Captain America), people flock to the cinema because it's superheroes.
In Germany at least, they try not to mention the name of Captain America in the title at all. Case in Point:
Captain America: The First Avenger
The Return of the First Avenger (a.k.a. Captain America: The Winter Soldier)
The First Avenger: Civil War (a.k.a. Captain America: Civil War)
Maybe, because they think "If we never mention the characters name, maybe our audience will forget about his name".
But then again, german movie titles ALWAYS get turned to whatever the hell Execs want them to be.
Disney has marketed Captain America as an Avenger after release of 2012 The Avengers movie. And also as "From studios that bought you Marvel's Avengers!".
While before that it war marketed as "From the Studios that bought you IRONMAN!".
Till the release of Civil War Captain America it self became a brand so it was not marketed as above two strategies rather than it was "Divided we fall!", "Captain America 3", while the posters of Civil War almost resembled an Avengers type gathering so people were attracted to it. Specially some posters feature Ironman vs Captain America which was also a USB.
