Well, that didn't take long. We admittedly haven't paid very much attention to Michael J. Fox's big TV return in 'The Michael J. Fox Show' since its premiere, but somehow, we imagine their latest stunt casting arrives to address exactly that. Michael's famous 'Back to the Future' co-star Christopher Lloyd will once again reunite with the former Marty McFly for an upcoming episode, but can they really take us back in time?
