Despite much publicized cuts in its staff, including the firing of regular correspondents Rob Stafford and Edie Magnus, Dateline NBC is being expanded to three nights per week beginning December 26. The network said that it will add a Tuesday-night edition of the news magazine on that date and will switch the Saturday edition back to Sunday at the conclusion of the NFL football season. It will continue to air a Wednesday edition. Meanwhile, ABC is resurrecting Primetime tonight (Thursday), including excerpts from Diane Sawyer's interview with Mel Gibson that originally aired on Good Morning America last month. An ABC blurb indicated that in the interview Gibson will plug his forthcoming film Apocalypto and describe how making "a film about the fall of an empire helped him face his personal demons."
