Iron Man may be B-list compared to the likes of Spider Man and Bat Man but folks hungry for a superhero couldn't care less. The first big flick of the summer took in over $100 million in its opening weekend.

A lot of fans watched Robert Downey Jr. kick evil butt as Iron Man, but only those who stayed past the credits got the whole story. You see, after the credits roll those viewers who were big enough Iron Man fans to stay, are treated to an even bigger surprise.

After the credits, Colonel Nick Fury (Samuel L. Jackson) asks Iron Man if he thinks he's the only superhero (a rhetorical question, we assume). Fury then says he needs to talk to Iron Man about "the Avenger Initiative."

After word of the bonus scene started to spread, searches surged on Mr. Jackson and his character, Nick Fury. Also spiking were lookups on "marvel avengers," "who are the avengers" and "avengers roster."

Those who wonder how the Avengers would stack up against other comic book crews typed in "avengers vs. x-men" and "avengers vs. fantastic four." Members including Thor, Captain America, and Ant-Man also posted impressive gains.

And though it's already a foregone conclusion, lookups on "iron man 2" soared into the thousands.

No question Iron Man is destined to be a Blockbuster series of movies and if the SpiderMan or Batman series are anything to go by, then Iron Man 2 will likely be even better than the original.
