Throughout the history of TV, most sitcom characters have been almost identical (visually) to the actors who portray them and I believe the vast majority of actors portraying sitcom characters have been at least a recognisable as their offscreen selves.
However, a number of sitcom characters have borne scant resemblance to their underlying actors.
To illustrate my point, I give you:
On the left, we have Isa Drennan from the utterly sublime Scottish sitcom "Still Game".
At the risk of appearing unwoke, I have to say I most definitely wouldn't.
On the right, we have Isa before she went into the make-up room: the spectacularly talented comedy actress, Jane McCarry.
I shall say no more.
