Chris Evans has insisted he isn't worried about superhero fatigue in cinemas, because Marvel knows how to satisfy fans.
The actor dons Captain America's mask and shield a fifth time for the latest movie Captain America: Civil War.
"Luckily, the movie is good," he said. "If you were all rallying around and working toward and sweating for a bad product, I think that's how you begin the initiation of disillusionment and apathy...
"As long as Marvel is making good movies, I'll still have the excitement and enthusiasm and commitment to work for them."
Lower-than-expected box office takings for DC Comics' Batman v Superman: Dawn Of Justice earlier this year sparked some speculation that audiences may be tiring of superhero movies.
But enthusiastic early reviews suggest things could be different for Captain America: Civil War.
The movie is due to open across America this Friday and Fandango has reported that advance ticket sales have already broken the site's record.
Civil War features most of Marvel's Avengers, including Iron Man (Robert Downey Jr), Hawkeye (Jeremy Renner), Black Widow (Scarlett Johansson) and Falcon (Anthony Mackie). Their superhero union is fractured when Iron Man agrees to -- and Captain America rebels against -- government oversight of the Avengers.
The film also introduces a new character, Black Panther (Chadwick Boseman), who's set to star in his own Marvel movie in 2018.
