IMAX hosts midnight screenings of the new Batman movie and Heath Ledger's swan song, The Dark Knight. Christian Bale returns as the Caped Crusader, Ledger is The Joker, and Maggie Gyllenhaal replaces Katie Holmes as Rachel Dawes. The biggest draw? Six sequences filmed with IMAX® cameras, with 35mm scenes appearing letterboxed and those shot with IMAX's cameras expanding vertically to fill the entire gigantic screen. Midnight, Channelside Cinemas IMAX, Tampa, channelsideimax.com; and Muvico Baywalk 20 IMAX, St. Petersburg, muvico.com.
