Marvel Studio's current plan is to convert Thor into 3D once the film is completed, and the recent footage shown at Comic-Con was presented in this format. Captain America: The First Avenger is also set to be converted into 3D, with its effects being rendered instead of converted. Now word comes from Showbiz 411 that Joss Whedon will actually be shooting The Avengers using 3D equipment as opposed to converting the film once it has been shot.
This will be the first time Marvel Studios has actually shot a film in the popular 3D format. Whedon and the studio have hinted for some time that The Avengers would be presented in 3D. Showbiz 411 is reporting that efforts to actually shoot the film instead of converting it are a "done deal".
The 3D news hasn't been confirmed by Marvel Studios as of yet, and we'll be sure to keep you posted with any further news on The Avengers as soon as we have more information.
