In 2010 they released Iron Man 2, the sequel to the 2008 Marvel Studios hit where Robert Downey Jr returned as Tony Stark.
Maybe the movie Iron man 2 is considered one of the worst of Marvel studiosBut it seems there were internal problems in the movie studio and they rushed things too much.
Remember that when the Marvel Studios Cinematic Universe, there was a division between the cinema and comics section, but since Marvel Entertainment in New York they continued to command a lot and the conflict can be read in the new book The Story of Marvel Studios: The Making of the Marvel Cinematic Universe.
“The critical response to Iron Man 2 brought the study to a halt. Especially since the desire to speed up that movie had come from Marvel Entertainment in New York. The lesson Marvel Studios learned from its first sequel was simple but vital: Above all, always make sure there is a good creative reason for making a sequel.
Since then things have been taken calmly, although it must be recognized that there is some sequel like Thor: Into the Dark World (2013) who were not quite right either. But generally speaking, the second parts are usually much larger than the first.
Still it was a tremendous success.
Maybe Iron man 2 did not have the expected result, even so it raised 623 million dollars, much more than the first, since it only reached 585 million. However, the third part of the trilogy of Tony Stark (Robert Downey Jr) surpassed 1,214 million in 2013. So, it was proven that he was one of the most popular characters in Marvel studios.
Now we will no longer see Tony Stark in the movies, but at least he has left us an almost insurmountable legacy. The movie Iron man 2 can be seen currently in Disney Plus.
