I'd love to see him...
.. do a recurring role as Mycroft Holmes, the brother of Sherlock Holmes, in the series 'Elementary'.
It's a poorly-concealed secret that Laurie's character House was very loosely based on Sherlock Holmes... House/ Holmes, (pronounced "Homes").. Wilson/Watson.. he's crotchety & demanding, solves mysteries with sheer deductive brilliance, Holmes had his morphine & House had his vicodin....
I'd love nothing more than to see Hugh Laurie 'echo' his role of House, but with his own natural accent, playing the brother of the modern day Sherlock Holmes.
To be honest-- I'd have loved to see Laurie play Sherlock, himself... but I'll take what I can get!!!
Sometimes fires don't go out when you're done playin' with them.
