If the movie is following the original comic, and with Whedon’s statements we know he is a purist, then these events could lead to a story arc that ties in a very significant Marvel character. In the second Avengers comic, the Avengers seek out the Hulk and attempt to contain him which leads to a run in with Namor and the Atlanteans. This is a Marvel milestone because it sets the course for establishing the modern Avengers team that we see in this film. I may be wrong but it would be a VERY nice addition to the movie if Namor was introduced and please remember, this is just speculation. :)
Also we found out that a contest is being held by Uniqlo.com in which a lucky winner will attend the European premiere of the Avengers! Premieres such as this are usually reserved for those in the business and celebrity types but one of you guys might have a shot to attend and rub elbows with Joss Wheson, Jeremy Renner, or Robert Downey Jr.!
Now Hurry! Entry deadline is TOMORROW April 13th!
