While Hollywood continued to wrestle with the fallout of the Sony hacking scandal, the weekend box office offered the solace of a moviegoing truism: Hobbits sell. Peter Jackson's final installment of his six J.R.R. Tolkien adventures, 'The Hobbit: The Battle of the Five Armies,' debuted with $56.2 million over the weekend and $90.6 million since opening Wednesday, according to studio estimates Sunday. For an industry reeling from the cancellation of 'The Interview' and terrorist threats against moviegoers, Middle-earth provided reliable refuge. Another final installment in a trilogy, 'Night at the Museum: Secret of the Tomb,' opened in a distant second place. The Fox comedy, which features Robin Williams' final performance, took in $17.3 million, well off the pace of previous franchise entries. The franchise's previous debut was $54.2 million for 2009's 'Night at the Museum: Battle of the Smithsonian.'
