Most astonishing visual transformation?

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.

Caroline Aherne was very attractive I thought,not as Mrs Merton though.

Phwoar! If she's good enough for Hooky...
Jennifer Saunders is pretty versatile. Did I ever mention Happy Familes?

Clive Dunn - Corporal Jones
David Jason - Blanco

Adil Ray as Citizen Khan was quite elaborate, and Sanjeev Kholi in Still Game.

Keith Lard
Paul Le Roy
Brian Potter
Max

From Phoenix Nights

Tommy Saxondale

Joan Sims as Gran in "Till death us do part"

And of course. Michael Bates as Rangi Ram in "It ain't half hot mum"

Paul Whitehouse had some different characters in the Fast Show too,I think.
