NBC has tweaked its Thursday lineup, adding the rookie show Kath & Kim to its comedy block in the plum 9:30 p.m. slot following The Office.

The mother-daughter comedy, starring Molly Shannon and Selma Blair, will debut Oct. 9, replacing a previously announced series of election-themed Saturday Night Live specials. It was originally scheduled to air Tuesdays following The Biggest Loser.

The network also has opted to stick to a traditional rollout, launching the bulk of its fall lineup during premiere week, beginning Sept. 22, and to put on the new reality competition series America’s Toughest Jobs earlier than planned.

There had been speculation that NBC might use its Aug. 8-24 Summer Olympics coverage as a springboard for an early fall rollout. Instead, the network will hold off, saving originals for the regular season and avoiding going head-to-head with Fox, which already has slotted several high-profile season premieres for the week of Aug. 25.

The first Monday of NBC’s season will be a full night of Heroes, a clips show leading to a two-hour season premiere.

Also slated to launch during premiere week are Law & Order: SVU on Sept. 23, new drama Knight Rider and Lipstick Jungle on Sept. 24 and comedies My Name Is Earl and The Office — which will return with one-hour premieres — as well as ER on Sept. 25. Sophomore comedy-drama Chuck and new drama My Own Worst Enemy will join Heroes on Sept. 29, while Life will return for a second season Oct. 3.
