Talent holding deals are pretty rare these days, especially with young up-and-comers. CBS and CBS TV Studios have signed such as deal with 24-year-old British actress Lucy Griffiths. Under the pact, the network will cast her in a drama or comedy project. It marks Griffiths’ first U.S. gig. In the U.K., she is best known for doing the first 2 seasons of the BBC drama Robin Hood, on which she played Maid Marian. The actress, who recently starred on the West End in the revival of Tom Stoppard’s Arcadia, is with U.S.’ Paul Kohner and Principal and U.K.’s Hamilton/Hodell. CBS has been the most active on the talent holding deal front this season, inking pacts with Rob Riggle, Leah Remini and Kristoffer Polaha.
