William Franklyn. Actor: Top Secret. Debonair British actor at home on stage (since the age of 15), screen and TV. Initially, his roles tended to be dramatic but, by his 40s, he was increasingly playing tongue-in-cheek comedy parts. His smooth lounge-lizard voice has frequently been used for voice-overs on television advertisements (most famously a long-running campaign for Schweppes drinks) and TV trailers.
