Vacationing on St. Bart's in the Caribbean, Rupert Murdoch opened a Twitter account over the weekend and promptly used it to promote two movies that units of his News Corp have released. "I LOVE the film 'we bought a zoo', a great family movie. Very proud of fox team who made this great film," he tweeted, referring to executives of his 20th Century Fox studio. (Professional critics have indicated that the film falls quite short of "great." Later "Saw Fox film Descendants. Thank God, one to be proud of. Star Geo Clooney deserves Oscar, maybe film too." The Descendants was released by Murdoch's Fox Searchlight unit. Murdoch made no mention of the British telephone-hacking scandal that has shaken his media empire over the past year or so, but several of his new-found Twitter followers did. Former Deputy Prime Minister John Prescott, whose own voicemail was hacked by a reporter and a private detective working for Murdoch's now-abandoned London tabloid News of the World , tweeted "Welcome to Twitter... @rupertmurdoch. I've left you a Happy New Year message on my voicemail!" Prescott also twitted Murdoch with this tweet "Hey @rupertmurdoch. I'm surprised you're only following two people. The police said it was at least 800 [the number of people whose voicemails were hacked by Murdoch's men]." Earlier in the day, Murdoch had reportedly tweeted, "Maybe Brits have too many holidays for broke country." His wife, Wendi Deng, fired back, "RUPERT, delete tweet." He did.
