Zack Snyder's upcoming pic Sucker Punch 3D will be released in the expanded IMAX format simultaneously with its regular release on March 25, 2011.  THR reports this is part of a 20-picture distribution deal between Warner Brothers and IMAX lasting through 2013.  The film is a 1950s period piece that tells the story of an institutionalized girl who retreats to an alternate reality to devise a means to escape the asylum.

Snyder is no stranger to IMAX releases -- his last film, Watchmen, had a similar distribution -- so I trust the finished product will look and feel really immersive in its full aspect ratio.  One can only hope IMAX 3D prices will retreat a little between now and next March, what with the number of films being rolled out.

If you're going to Comic-Con this year, Snyder has said to expect footage from the movie.
