Lifetime’s Gabby Douglas biopic scored 3.8 million viewers Saturday — a strong showing for the cable net but falling short of the network’s previous two weeks’ worth of Saturday movies starring an ax murderess and siblings locked in an attic. That said, The Gabby Douglas Story, about the Olympic gold medalist who become the first African American to be named individual all-around champion in artistic gymnastics at the Olympic Games, was the most tweeted program of the night across all of television, excluding sports, according to Nielsen SocialGuide. Two weeks earlier, Lifetime’s unveiling of Flowers In The Attic, based on the V.C. Andrews novel of same name and about siblings locked in an attic by their mother and even worse grandparents, logged 6.1 million viewers, which was ad-supported cable’s most watched original movie since November 2012. Lifetime already has ordered the sequel, Petals On The Wind. The following week, Lizzie Bordon Took An Ax bagged 4.4 million viewers, becoming the night’s most watched cable telecast and the most watched telecast across all of TV in key female demos.
