Re: MCU Phase 3: Have it your way
I think all the Marvel Phase movies should be rich with cameos from many of the other Marvel superheros. I'm not saying a bunch of them in each movie but do it smartly so each movie feels like its more than just a movie about the title character.
If Marvel does this correctly then each Marvel Phase movie will be a big event and make Iron Man 1 & 2 money at least. I predict that if they can give them each a MCU feel then box office will slowly increase with each movie as a build up to the big payoff with the Avengers movies.
