Chris O'Dowd has signed up to write and star in a new comedy for Sky1.
Moone Boy, which is adapted from O'Dowd's previous Little Crackers episode, is a semi-autobiographical show about O'Dowd's time growing up in Ireland in the 1980s.
It follows Martin Moone, an 11-year-old child with a vivid imagination. O'Dowd will star as Martin's imaginary friend Sean Murphy.
The show is expected to include animation as Martin's drawings appear to come to life.
Steve Coogan and Johnny Vegas are among the stars who have signed up for guest roles in Moone Boy, but the lead role of Martin has not yet been cast.
"It's a really funny show which has loads of animation and a number of laughs that I hope people will love," O'Dowd said. "It was essential to film in Ireland and what was great about Sky was they wanted us to film here and they were really supportive. That wouldn't have happened at any other channel."
Meanwhile, Sky's head of comedy Lucy Lumsden said that she is "delighted" O'Dowd agreed to write a series, saying: "With [co-writer] Nick Murphy, he's written six brilliantly funny scripts. Sky customers are in for a treat."
In October, it emerged that O'Dowd's previous comedy series The IT Crowd will not be returning for another series. More recently, he starred in the television show The Crimson Petal and the White and the hit movie Bridesmaids.
Filming for Moone Boy is expected to begin in Dublin and O'Dowd's hometown of Boyle in January, while the show is due to air on Sky1 in the summer.
