Not long after the downtown IMAX next to the Aquarium shut down, we got wind of plans to build a new one in West Ashley. Southeast Cinemas, a company out of Charlotte, is constructing a new 16-screen cineplex on the site of the old Citadel AMC. Don't worry about getting the same old fare. IMAX technology has come a long way since movies about roller coasters. It's digital, for one thing. 3-D, for another. Anyway, Hollywood is making movies, like The Dark Knight, with IMAX in mind. Southeast Cinemas says the new theater will likely be done by the summer blockbuster season.
