I've enjoyed Samuel L. Jackson's Nick Fury in the Marvel films. He's a great character that's also helped tie everything together leading up to The Avengers, which is where he had his biggest role. It sounds like he'll also have a bigger role in Captain America: The Winter Soldier. In a recent interview with Comingsoon he talked about the character saying,
Everybody likes a franchise character. Bruce (Willis) had his and Sylvester Stallone had Rocky, so I like coming back to Nick Fury. Nick Fury's a great guy.
The site then asked him if we'd ever see a Nick Fury movie that will give us some background on the character to which Jackson replied,
I think a lot of people know that. I know him as something else because I've been alive longer than most of the fans that watch the movies so I know Nick Fury as the World War II veteran and all that stuff. It might be interesting to do one day but we find out little bits and pieces about Nick and we're going into Captain America 2 in late March.
He then confirmed that Fury does have a bigger role in the Captain America sequel. The movie is going to have a good deal of World War II flashbacks, and it sounds like we are going to see some backstory on Fury during that time period, which will be awesome! It makes sense that it would be included in this story. The movie will also give us some backstory on Black Widow. I don't think Fury really needs his own movie, because he can show up in any storyline that he's needed in. But, if it did eventually happen I wouldn't complain.
