Cheers to The Last Song star Miley Cyrus, whose first cinematic foray out of the Hannah Montana bubble opened yesterday to No. 1. Her two-day head start on Clash of the Titans grossed $5.1 million on 2,673 screens, capitalizing on spring-break crowds and the early fade of How to Train Your Dragon, which trailed Song by more than a half-million dollars in nearly 50 percent more theaters. Ouch. Release the Kraken, indeed. [Box Office Mojo]
