You must be very young - Rowan Atkinson first became famous in the early 80s on a TV show called "Not the 9 O Clock News" - a sort of Monty Pythonist sketch show he did with, Pamela Stephenson, Mel Smith and Griff Rhys Jones.
I am 42... LOL I am glad you think I am young. I only know the Mr Bean series, my kids love them. Now I remember the Black Adder TV series... he speaks in them.... I only stayed for 6 years in the UK so am not that familiar with British TV. American programs and cinema took over the world of entertainments obviously.
