Catch a Sneak Peak at Spider-Man 3

On Monday, March 5th, NBC will air an exclusive clip of "Spider-Man 3" during "Heroes" that has never been seen before. And then, after the clip airs, you can go to NBC.com for an extended High Definition clip.

NBC’s latest successful series "Heroes" is an all too fitting venue for the promotion of fresh footage of the webslinger in the biggest chapter of his big screen saga yet. Episodes of "Heroes" are streaming online for those who are late to the hunt for the emerging superhumans. If you just want to tune in to see "Spidey," the show begins at 9PM Eastern Time.
