I never thought about this, but yeah! Captain America and Black Panther have already hit 1 billion, both the avengers movies are guaranteed to hit that point, Captain Marvel will do well, I figure ant Man will do better than its predecessor, and yeah!
Strange to think that Doctor Strange - a wonderful film with great characters and some of the most interesting and unique visuals of the past decade - is going to be the lone film bringing the whole endeavor down.
