Starlings - featuring Brendan Coyle and Lesley Sharp - will return for a second series in 2013.
The show - created by and also starring Matt King (Peep Show) and Steve Edge (Star Stories) - has received an order for eight more 60-minute episodes.
The broadcaster's popular anthology series Little Crackers will also return for a third run this Christmas.
Stars confirmed for the latest strand of short films include Katy Brand, Paul O'Grady, Jason Manford, Alison Steadman and Joanna Lumley, who will also direct her film. Further names will be announced in the near future.
Chris O'Dowd's semi-autobiographical comedy Moone Boy - inspired by the comic's own Little Crackers episode - has also been renewed, before the first series has even aired.
Set in a small Irish town in 1989, the series follows spirited 11-year-old Martin (David Rawle) and his imaginary friend (O'Dowd), with the first run of episodes scheduled for September.
Sky1 have also announced that Charlie Brooker's cop drama spoof A Touch of Cloth will return for another two-part special and a two-hour TV film.
