The Black Adder and there is a character that came on that looked familiar to me. I asked Jachen if it was the actor from Dumb and Dumber...but that couldn't be right...I could picture seeing him talking recently. Then I realized it was Sir Anthony from Downton Abbey! So in conclusion these two are basically twins/should be related.
I used to get Jeff Daniels and Dave Coulier confused...for some reason...now we got Robert Bathurst in the mix. Tricky. Two other celebrities I used to get mixed up, here.
