HBO has made a deal to develop the Oscar-nominated comedy The Kids Are All Right as an hour-long series. Lisa Cholodenko, who co-wrote and directed the Focus Features release, will write the pilot script. I’m told that it will continue the adventures of the five main characters. They were the same-sex partners (played in the film by Annette Bening and Julianne Moore), their son and daughter (played by Josh Hutcherson and Mia Wasikowska) and the biological father of the kids/sperm donor who surfaces and tears the family apart (played by Mark Ruffalo in the film).
