LOS ANGELES (thefutoncritic.com) -- FX is delaying the launch of its animated comedy "Archer" until January.

The six-episode series, which spoofs the spy genre, had originally been set to follow "It's Always Sunny in Philadelphia" on Thursday nights this fall. The network cites the show's lengthy production process - each episode takes about a month to produce - as the reason for the delay. FX however will quietly air the premiere installment this Thursday at 10:30/9:30c following the season premiere of "Sunny." Said stunt, which won't be promoted or listed in program guides, is described as "purely a sampling opportunity."

In addition, the network has asked for four additional scripts of "Archer" to potentially extend its freshman run. Aisha Tyler, Chris Parnell, Jessica Walter, Jon Benjamin and Judy Greer are among the show's voice ensemble. Adam Reed created the series and is executive producing.

Meanwhile, fellow newcomer "The League" is still on track to roll out this fall. The series, about the members of a fantasy football league, will follow "Sunny" on Thursdays at 10:30/9:30c later this year. An exact date will be announced soon.

Mark Duplass, Steve Rannazzisi, Nick Kroll, Paul Scheer, Jon Lajoie and Katie Aselton co-star in the half-hour, which comes from executive producers Jeff and Jackie Schaffer.
