Sumner Redstone isn't done deriding Tom Cruise. In a new Vanity Fair feature, the Viacom chief says Paramount's onetime tentpole-hoister was "embarrassing the studio," and "costing us a lot of money." How much did Tom's Kate-induced antics supposedly affect box office? To the tune of "$100 million, $150 million on Mission: Impossible III," Redstone surmises. "It was the best picture of the [franchise], and it did the worst."
