Among many of the services that "Game Of Thrones" has done (boosting George R. R. Martin's book sales, keeping the fake blood industry alive, etc etc), perhaps the greatest is giving new leases of life to veteran stars. The show's hugely expansive cast features a host of recognizable faces, but given the series' enormous popularity, it's likely that people like Diana Rigg, Stephen Dillane, Iain Glen et al are winning over new generations of fans.
