It's official: Avengers has the most successful opening weekend ever. (Not adjusted for inflation.)

In case you were still wondering whether this Avengers thing would catch on with the kids... The big Marvel team-up movie amassed over $200 million in its opening weekend, for a bigger debut than the last Harry Potter movie, The Dark Knight... or any other movie, ever. (In non-inflation-adjusted terms.)

Part of the reason for the huge box office? Over half of movie-goers chose to see The Avengers in 3-D — and to be fair, the 3-D conversion was actually pretty decent, especially compared to most other post-conversions thus far.

Avengers now has a global box office total of $641 million, according to Box Office Mojo, and is easily on track to join the select club of movies raking in over $1 billion at the global box office. [L.A. Times]
