NEW YORK (AP) - Rob Lowe has a hit playing J.F.K on National Geographic Channel. The "Killing Kennedy" film, with Rob Lowe portraying the President John F. Kennedy, was watched by 3.4 million people Sunday night. According to the Nielsen company, "Killing Kennedy" is the most-watched show ever on the network, by a mere 3,000 viewers. The film edged last winter's telecast of "Killing Lincoln" about the assassination of President Abraham Lincoln. Both assassination efforts are based on books by Fox News Channel's Bill O'Reilly. Production is to start early next year on "Killing Jesus."
