Extra $5 for fake IMAX? Beam me up, Scotty

If you're paying an extra $5 to see the new "Star Trek" movie on an IMAX screen, you're getting ripped off if it's not the huge IMAX screen you're used to.

Some theaters that claim to have an IMAX screen, and charge $5 more to get in, are showing the movie on a screen that is slightly larger than a regular movie screen, but not as big as the 76 feet by 97 feet screen that IMAX customers have come to expect, according to a blog by Los Angeles actor Aziz Ansari.

Ansari went to see the "Star Trek" movie at a theater in Burbank, CA, on Monday and found that the $5 surcharge didn't get him into a big-screen theater, but to one that is slightly larger than normal. AMC and Regal theaters across the country are doing this, he found.
