On MTV Movies Blog, Shawn Adler gives us the latest Samuel L. Jackson/Iron Man scoop:

That Samuel L. Jackson will play a Nick Fury for a cameo appearance in the upcoming Iron Man movie is just about the worst kept secret in comic-dom, somewhere just south of “Jeff Bridges will play Iron Monger” and just a little less obvious than “Iron Man will fly.”

Heck, super producer and Marvel movie mastermind Avi Arad himself let it slip to MTV News nearly seven months ago. As in, LAST July.

“The Sam thing was supposed to be the biggest secret of them all,” Arad told us then, clearly frustrated. “It’s amazing how it got out.” See? It’s right there! That makes it what we call “old news.” But if you think that also makes it undeniable, well, than you clearly have never met Samuel L. Jackson.

“I asked Avi Arad about that and he said he didn’t do that,” Jackson coyly responded when asked about what Arad told MTV about the Nick Fury cameo. “He told me he didn’t.”

It would all be endlessly frustrating, of course, if we didn’t, you know, have these things on video tape.

“Well [then] I am indeed Nick Fury,” Jackson finally admitted, officially confirming his role for the first time. “But I don’t know if I’m gonna be in [Iron Man] though.”

So you haven’t shot any scenes?

“I can’t tell you that!”

You won’t confirm?

“I won’t confirm!”

Head, meet brick wall. Brick wall, meet head.

But give Jackson credit – the man clearly knows how to keep a secret. Too bad he confirmed he’s Nick Fury (sucka!)
