Although Disney devoted a good chunk of its CinemaCon presentation today to talk of Star Wars and The Avengers and clips of upcoming movies including first looks at the live-action re-telling of Cinderella and Pixar’s Inside Out, theater owners left the near three-hour session really singing the praises of one of the lesser-known films on the slate: the May 16 release Million Dollar Arm. It stars Mad Men’s Jon Hamm, who received the convention’s Excellence In Acting award from studio Chairman Alan Horn just before a full screening of the movie, which Horn told the crowd has scored higher than any movie he has ever tested at Disney, or Warner Bros before that. “And that includes the first Harry Potter, which was so highly anticipated,” he said. Judging from the reaction in the Caesars Palace Colosseum theater and comments afterward, those test scores would seem to be justified. This is the kind of increasingly rare non-animated family film that should play across the board. “It’s comical, it’s emotional, it has great music” was what one exhibitor was heard saying as he walked out. That music, by the way, is from two-time Oscar winner A.R. Rahman, who scored Slumdog Millionaire.
