As for having the different universes of the films mesh together, we heard from Branagh's camp a while ago that his Thor movie will be based in science. What that means is anyone's guess in terms of the movie but it will help make it more believable when our heroes join together to fight evil.
Before that happens though, we have the eagerly anticipated Iron Man 2 coming up next which also features a pretty big roster of characters. Could we be seeing our first look at Thor or Cap in that film? According to Iron Man director Jon Favreau's Twitter, he met Thor director Kenneth Branagh last week and pumped him his work on the project. That project by the way, is the one I'm most looking forward to and I couldn't be more excited to know that Branagh is helming it, especially knowing that he's 100% in on the interconnectivity of the Marvel movies.
"Had lunch with Kenneth Branagh. Wonderful fellow. He's going to do a great job on Thor."
Thor's star Chris Hemsworth screen-tested with Robert Downey Jr. and now with Favreau spending some time with Branagh, it's very possible that there will be a Hemsworth cameo in Iron Man 2 which may help launch Thor's debut the following summer. And let's not forget the widely speculated but denied rumor that Ed Norton could make a guest appearance as Bruce Banner/Hulk.
Don't be surprised to see something special from Iron Man 2 in terms of cameo appearances, each film from now on will tie-into or help seed the following projects. They'll be taking advantage of every opportunity to cross-market and help establish the shared continuity in preparation for The Avengers.
Zak Penn is currently still writing the screenplay and trying to make it work with the stories of Iron Man, The First Avenger: Captain America and Thor. We still don't know who will direct The Avengers but we do know that Jon Favreau won't be. He'll be producing the movie and no doubt be working on an Iron Man 3 around that time which works for me.
So, from all accounts, it seems that the scripts and stories are all coming together very nicely for Marvel's slate of upcoming films and I hope those chosen to bring us The Avengers take advantage of the great work that's been done so far. We have a lot to look forward to.
