Iron Man 2 already playing in some areas and top-secret ending revealed?

According to THR, Marvel Studios’ Iron Man 2 has already launched internationally with No. 1 openings in six markets for a total $2.2 million from 960 venues. France led the way for Paramount, contributing $1.6 million to the tally.

Iron Man 2 hits U.S. theaters and IMAX next Friday, May 7th.

In more Iron Man 2 news, FlickCast reports that a top-secret ending has been revealed from the film, again signaling the penultimate Avengers movie, coming to theaters on May 4, 2012.

This won’t ruin the movie for you, but fanboys might not be too happy to know about this just yet.

WARNING: POSSIBLE MAJOR SPOILER AHEAD

Apparently after the credits of Iron Man 2, a scene involving Agent Coulson (Clark Gregg) climaxes to reveal…

Mjolnir, Thor’s hammer.

Now I have no idea is this is for real, but with the overseas release confirmed, it’s a good possibility. FlickCast even has a screenshot of the hammer itself.
