I think you're bound to get a sense of any character that you play. It's not something you often do in comedy.
It's the difficulty we had with Mr. Bean, actually, when it went from TV to film. You certainly discover that you need to explain more about a character.
I have always regarded Mr. Bean as a timeless, ageless character, and I would rather he be remembered as a character mostly in his 30s and 40s.
When I was doing Bean more than I've done him in the last few years, I did strange things - like appearing on chat shows in character as Mr. Bean.
I would return to the Blackadder character if the opportunity came up. I have no qualms about that at all.
