EXCLUSIVE: Shine International has closed a deal with PBS on Will & Grace exec producer Gary Janetti’s British sitcom Vicious. The public broadcaster will air Vicious in the U.S. next year. The initial six-part series premiered on ITV in April and at the time was the highest-rated comedy launch on any UK channel in 2013. It went on to hold an average of about 3.4M viewers. Veteran British thesps Ian McKellen and Derek Jacobi play a constantly bickering couple who’ve lived together in a small Covent Garden flat for nearly 50 years. But underneath all their vicious co-dependent fighting, they deeply love each other. Harry Potter‘s Frances de la Tour and Game Of Thrones‘ Iwan Rheon also star. The show was given a second-season order by ITV in August and Shine America has been exploring a U.S. version. Vicious is a Brown Eyed Boy production in association with Shine’s Kudos and Nickelby Inc. The deal was brokered by Matt Vassallo, Bill Gardner, and Jack Dougherty on behalf of PBS.
