While no one knows for sure when Christopher Nolan’s follow-up to “The Dark Knight” will begin filming, the next big-screen Batman chapter might be bigger than you think – like IMAX big.

Nolan gave us all a taste of what specially shot IMAX footage could do for superhero films when he used the format for a few key scenes of “The Dark Knight.” The format even inspired Jon Favreau to ponder IMAX for “Iron Man 2.” Now, a breaking rumor indicates that Nolan may be considering a total IMAX approach as he heads toward his third installment of his renewed Bat-Franchise.

According to the usually reliable crew at AICN, the next film, which has yet to receive an official title, could be completely shot in IMAX. If the report turns out to be true, every scene would be getting formatted from the first day of shooting to be spread across super-wide screens everywhere.

There is speculation that Nolan may have even been developing new cameras and techniques during work on his most recent film ‘Inception‘, experimenting with specifications that could be used when he returns to Gotham City.
