CBS will again air “E.T. The Extra-Terrestrial” on Thanksgiving night, this time followed by a preview of the upcoming Steven Spielberg movie “Jurassic Park.”“E.T.” made its broadcast TV debut on Thanksgiving last year, flying off with a stellar 18.4 rating, 34 share in Nielsen. Universal sold broadcast rights to Sears under a 10-year deal and the retailer, hoping to make the movie a holiday perennial, will again sponsor its telecast as a “Sears Family Theater” presentation. Separately, CBS filled in a couple of holes in its November sweeps arsenal, setting made-for “Overkill: The Aileen Wuornos Story” (about the female serial killer) and theatrical “Lethal Weapon 2″ for its Tuesday movie slot Nov. 17 and Nov. 24, respectively. The network previously announced its five-hour Frank Sinatra bio-miniseries will air Nov. 8 and 10 and its Betty Broderick telefilm sequel for Nov. 1.
