The two-hour premiere last night of Frank Darabont’s LA Noirish limited event series pulled in 2.3 million total viewers for TNT. Debuting at 9 PM, the heavily promoted Mob City drew 801, 000 viewers among Adults 18-49 and 875,000 viewers among the Adult 25-54 demo. While something quite different for TNT as a limited event series, and with good potential digital life, Mob City’s results last night are at the top end between the cable station’s two most recent debuts Monday Mornings and King And Maxwell – both of whom have since been cancelled. The David E. Kelly medical drama pulled in a weak 1.34 million total viewers at 10 PM on February 4 this year with just 386,000 among Adults 18-49 and 472,000 among the 25-54 demo. The Rebecca Romijn and Jon Tenney P.I. drama drew 3.5 million total viewers with 825,000 among Adults 18-49 and a bit more than 1 million among Adults 25-54 on June 10. Mob City is based on John Buntin’s book L.A. Noir: The Struggle For The Soul Of America’s Most Seductive City. Starring Neal McDonough, Ed Burns, Milo Ventimiglia and Jon Bernthal, the one-hour six-episode series is set to run until December 18. Like the LA Noir book, Mob City focuses on the war between the Police Chief William Parker’s LAPD and newly transplanted gangsters like Mickey Cohen for control of LA during the 1940s. TNT picked up the drama from the former Walking Dead showrunner and fellow EP Michael De Luca with a 6-episode order in October 2012.
