In my opinion, I think that Atkinson is a very skilled comedian, actor, and writer. I love Black Adder and watched the Black Adder's Christmas Carol over the holidays. His Mr. Bean character is difficult for me to watch as he makes me nervous, though I do enjoy Mr. Bean's Holiday with him bumbling through France.
I didn't realize that he participated in The Secret Policeman's Balls. We used to have this on VHS and will have to get the DVD. Another blast from the past that I'd like to have is The Best of Not the 9 O'Clock News. We loved the comedy shows on BBC Radio 4 that would later become TV shows (such as Yes, Minister).
Perhaps you received an Amazon Gift Certificate that you'd like to redeem or, if not, just plonk down your plastic to get one of these :)
Here's the YouTube video I watched yesterday. It is a brilliant spoof of Doctor Who performed for a Comic Relief Red Nose Day telecast in 1999, Doctor Who and the Curse of Fatal Death. Starring: Rowan Atkinson, Richard E. Grant, Jim Broadbent, Hugh Grant, Julia Sawalha, Jonathan Pryce, and, must not leave out Roy Skelton who is the voice of the various Daleks.
There is a wikipedia page about it HERE.
Have a great day!
