Cap doffs his hat

Captain America and Iron Man may not always see eye to eye but Chris Evans — who plays the Cap in the Marvel Cinematic Universe — is all praise for Tony Stark, a.k.a Marvel co-star Robert Downey Jr. 

Evans says Downey Jr is “irreplaceable” as Iron Man. Evans plays the role of Steve Rogers/Captain America in the universe. Both the actors will reprise their respective roles in Avengers: Infinity War and Avengers 4, which is presumed to be their last film in the franchise. 

Speaking with Comicbook.com, Evans said: “It’s low-hanging fruit to say (Robert) Downey. He’s such a wonderful guy and is so talented, so experience, and so supportive. He’s always been in my corner and I’ve always felt supported by him. No matter what it feels like for me, I try to imagine what it feels like for him, because he really did start this. He really is so irreplaceable. Nobody can ever be Iron Man. It’s not a role like Superman or Batman that can kind of find different incarnations, no one can touch it.”
