In a story from SCI FI Wire, director Joe Johnston (The Wolfman) recently discussed the casting of The First Avenger: Captain America.

"We need to cast it soon," Johnston said. "We have a very short list, but we're still juggling actors here. I'd say within the next couple of weeks we'll have ourselves a Captain America, I hope."

Aside from this quote, Johnson was very noncommittal about actual specifics on the film. He said that shooting probably won't happen "until the end of June."

"But we're getting ready to go to the U.K., it looks like.".

As for the story or plot of The First Avenger: Captain America?

"And the interesting thing about this guy is that he starts out as a 98-pound weakling and he becomes this Adonis. How does that affect his arc in the story? How does that affect where he goes and what happens to him and everything? I think that's the part of the story that was fascinating for me. And, of course, being a Marvel movie, there's fantastic action scenes in it and all kinds of great stuff. But there's an interesting story there as well."

The First Avenger: Captain America is slated to hit theaters July 22, 2011 from Paramount Pictures and Marvel Studios.
