Also Sunshine was a great movie and it was directed by Dany Boyle, it didn´t work in the box office but that happens to a lot of movies and then he has done other smaller projects, but also worked with people like David Ayer in street king that movie is full of great actors, didn´t do great at the box office, and he is known to do a great acting job in all the small indies he is in (Puncture/ The Iceman), of course he has done some popcorn stuff like the FF (which were bad, but a lot of people said he was the one they rescued from that stuff) and the Losers and Push weren´t good at the end but by it´s cast, it is obvious they all went in thinking it would had been better projects.
Being Cap helped him become more famous, but at the same time it is what he didn´t wanted, he said he didn´t want that aspect of losing his anonymity and having paps and people talking, some actors just want to work and can´t deal with the other aspect and sadly for him, now he is deep into that exposure he didn´t wanted before.
I love him playing Cap and I hope he never stops playing that character for as long as these movies are around, but I can imagine being in Marvel is like being a TV actor, specially for him, once they did the first Cap movie, he only had one year off the character, which he did Snowpiercer (which took in pre and main production as long as a Marvel film) and then he could only fit a small film in between before he had to go work in Cap2, his directing debut had to be rushed in the times for pre and post production because he fit it between Cap2 and AoU and now he is back again about to play Cap.
I mean, it will be interesting to see what he does after Cap3, but I wouldn´t be surprised if he tries to stay away a little, to download on the exposure, any other actor in his position would probably take all opportunities with the studio and play the game, become a huge star, he doesn´t seem to deal well with that game play, so IDK, but obviously he has good enough rep in HW to have people wanting to work with him, which is probably why people in Marvel did their job to convince him to play Cap.
uf this went too long, sorry!!
