Director Brian Singer may add footage to the IMAX version of Superman Returns to take advantage of the 3-D process being employed in the giant-screen prints. (About 20 minutes of scenes are in 3-D.) Singer told today's (Tuesday) Los Angeles Times that he is considering restoring some footage at the beginning of the film showing Superman on the gutted planet Krypton. The Times observed that all of the 3-D scenes were created digitally in post production and that some persons attending a Los Angeles screening "were put off by a distracting blurring effect that crops up when the action crosses the screen at high speed." Nevertheless, the newspaper commented, some sequences "have an undeniable gee-whiz factor."
