Mark Cuban is reportedly exploring a possible sale of his movie theater group Landmark Theatres and independent film distributor Magnolia Pictures by putting them up for auction. In an email to The Hollywood Reporter, he emphasized that he still feels the companies are “a great business” and thatt he is “just testing the market.”

Magnolia Pictures is still doing brisk business, recently picking up the rights to the 2011 Tribeca Film Festival documentary Jiro Dreams of Sushi, and Landmark Theatres operates 55 cinemas with 245 screens in 21 cities, including New York, Los Angeles and Chicago.
