Hadlow also revealed at the festival that she was still searching for pre-watershed family comedies to replace Miranda on the channel.
Digital Spy revealed earlier today (August 23) that Rik Mayall and Adrian Edmondson were reuniting for a spinoff of their '90s hit Bottom, titled Hooligan's Island.
Based on the Bottom Live show, it features the programme's classic characters Richie Richard and Eddie Hitler, who have found themselves shipwrecked on a tropical hell hole.
The violent slapstick that made the original TV series famous is still prominent and a full six-episode run has been confirmed for 2013.
David Mitchell and Robert Webb's new show Our Men is based on the lives and loves of the British Embassy team in Tazbekistan.
Mitchell plays Keith Davis, the newly appointed British Ambassador of Tazbekistan, while Webb is cast as Neil Tilly, Deputy Head of Mission. A description of the show claims that the two leads are "far more likely to be drinking lethal vodka in the President's hunting yurt than having G&Ts on the lawn".
Meanwhile, Sue Perkins will branch out into the world of sitcoms with Heading Out, a show about incredible veterinarian Sara, who is struggling to tell her parents that she's gay. On the eve of her 40th birthday, Sara is warned by her friends that she has six weeks to tell her parents or they will tell them.
Heading Out will have a six episode run.
