Mark Cuban disclosed in a 13-D filed this morning that he has a 9.4% stake in Carmike Cinemas (NASDAQ: CKEC).

Unlike Mr. Cuban's personal blog, the 13-D lacks much in the way of color: There is the standard disclosure that he acquired the stake for investment purposes and may buy more or sell some or all depending on his mood.

According to the company, "Carmike Cinemas, Inc. is a U.S. leader in digital cinema and 3-D cinema deployments and one of the nation's largest motion picture exhibitors. As of September 30, 2008, Carmike had 250 theatres with 2,276 screens in 36 states. Carmike's digital cinema footprint reaches 2,147 screens, of which 430 are also equipped with 3-D capability. Carmike's focus for its theatre locations is small to mid-sized communities with populations of fewer than 100,000."

The company has been reporting huge losses as it sinks under the weight of a crippling debt load and economic malaise. But Cuban's one of the smartest people in business, so maybe there's some upside to be had. The shares have lost about 90% of their value since the beginning of 2007.

Shrek 3 and Spider-Man 3 are coming to a movie theater near you, just as the sector is coming out of an ugly downturn.

Overcapacity and over-leverage had led to an ogre-ish performance causing theater operators to file for bankruptcy or get picked up by private equity.

Now theater companies are going public or emerging from bankruptcy with little fanfare. However, according to Buzz Zaino, long-time great stock picker at Royce Opportunity Fund, it is time to start looking at these stocks again. In Barron's fund-manager interview (subscription required), Zaino said box-office receipts are up 7.2% year-to-date with a summer of good new releases expected to keep the momentum going.

Carmike Cinemas Inc (NASDAQ: CKEC) looks particularly attractive since it has upgraded 75% of its screens to digital, on which, in addition to showing movies, new alternative concepts are expected to generate additional revenue. Other movie chains Zaino likes are Regal Entertainment Group (NYSE: RGC) and Cinemark Holdings Inc (NYSE: CNK).

Expected improvements in box-office receipts should lead to nice incremental EBITDA margins especially for Carmike since its theater upgrade is mostly completed.

Few have mentioned theater stocks as a place to invest in. Zaino is one of the best at find long-forgotten industries as fundamentals are on the upswing. This ogre of an industry appears ready to return some princely profits to shareholder.
