Indeed he is, but to me Laurie will always be Lieutenant George.
Which reminds me of another series worth watching, Blackadder. British sitcom from the 80s whose four seasons are spread thru different periods in British history. The first series is set during the reign of a fictitious medieval king. The second, set in the Elizabethan era, is where Laurie joins the cast. The third series is set during the Georgian era. The final, and arguably best series, Blackadder Goes Forth, is set in the trenches of The Great War
