When we talk about actors who are BORN to play certain comic book characters, one of the names that come to mind is Robert Downey Jr as Iron Man. So, it’s difficult to imagine the MCU without RDJ playing the role of Tony Stark/Iron Man. 

In an interview with news.com.au, Robert Downey Jr discussed the possibility of him leaving the MCU.

Everyone says to me it’s like a glove that fits so well. I have to start over every time but I am starting over with a pretty solid base. I just never want to blow it for the last six or seven [movies] I have done by dropping the ball because I decided to go do it one more time. I just want to hang up my jersey before it’s embarrassing.

Spider-Man: Homecoming, featuring RDJ as Iron Man will hit cinemas on 7 July.
