'Parenthood' to return Sept. 13; 'Playboy Club' will bow Sept. 19

NBC has announced its fall premiere dates, with comedies “Up All Night” and “Free Agents” to receive a head start on their regular timeslots.

The Peacock is the last of the Big Four networks to divulge when it will begin to unfold its fall sked.

As has been the case the last few years, net is pinning much of its hopes on the NFL. Coverage begins with a half-hour kickoff special Sept. 8 before the season begins at 8:30 ET, when New Orleans plays the defending champion Packers at Green Bay. At the moment, however, the NFL is locking out its players, and there’s a distinct possibility the season won’t begin on time.

If the football season starts on schedule, NBC will air another NFL telecast three days later, when Dallas plays the Jets in New York on the 10th anniversary of the 9/11 terrorist attacks.

“Up All Night” and “Free Agents” will debut at 10 p.m. Sept. 14 following the season finale of “America’s Got Talent.” NBC is hoping a big “Talent” aud will stick around to sample the new laffers.

Also beginning that week: “Parenthood,” which launches Sept. 13.

Most NBC shows will debut the week of Sept. 19. On that day, a two-hour “The Sing-Off” will lead into new ’60s drama “The Playboy Club.”

The 12th cycle of “The Biggest Loser” starts Sept. 20, and “Up All Night” and “Free Agents” move to their normal 8 and 8:30 p.m. time-slots the following day. They’ll be followed by the season preems of “Harry’s Law” and “Law and Order: SVU” at 9 and 10 p.m.

Sept. 22 will mark the season launches of “Community,” “Parks and Recreation” and “The Office,” followed by the series debut of laffer “Whitney” at 9:30. Added drama to a comedy-filled night is Maria Bello starrer and U.K. import “Prime Suspect,” which begins at 10.

“Chuck” will begin its final season at 8 p.m. on Oct. 21, skedded to be an off day of the World Series. Following “Chuck” is the series premiere of sci-fier “Grimm.”
