That would be one hell of a Avengers ensemble right there!! Hugh Jackman, Ed Norton, Chris Evans, Doug Jones, Robert Downey Jr., Toby Maguire, and Chris Hemsworth get them all in and get this thing on film now!!
P.S. - Although, the only bit of casting from above that I think could have gone to someone else is Chris Evans as Captain America. I think Max Martini (THE UNIT Series) would have been a better choice. [link]
For anyone who has seen The Unit, you know he played a dynamic character both physically and emotionally and would have pulled off Captain American, not only perfectly, staying true to the character, but with relative ease as well. For those who haven't seen him, find an "Max" driven episode and sit back and watch as you confirm to yourselves what I already know!! MAX MARTINI FOR CAPTAIN AMERICA!!
