A peek on Jennifer Aniston's role as Jack's stalker, Oprah Winfrey as herself, Megan Mullally as a social worker and Steve Martin in Liz's high school.
Third season of "30 Rock" is coming on the way with a bang, and NBC have come up with a longer promo for it. The video compiles scenes of guest appearances presented in the episodes to come, like those coming from Oprah Winfrey, Jennifer Aniston and Steve Martin.
The season opener on October 30 will be opened with a cameo from Megan Mullally who acts as a social worker who evaluates whether Liz Lemon is qualified to adopt a child or not. There are also sneak peeks from the 3.02 episode of Oprah on a flight with Liz, trying to cope up with the eccentricity of Liz.
The November 13 episode sees Jennifer as Liz's former roommate Claire Harper, stalking Jack Donaghy. Steve meanwhile, will appear on the November 20 episode when Liz attends her high school reunion.
Additionally, there's also a clip from the first episode of the third season where Megan as the worker questions Liz's work mates for testimonies.
