Another thread got me thinking about whether many classic sitcoms would've been as acclaimed had they cast different or the original fist choice actors in the main roles. Was the success of these mostly down to the writing but the actors were potentially interchangeable or was the way the actual actors delivered the lines just as essential for the laughs. Kicking things off...
OFAH - I reckon Richard Beckinsale would've made a great Rodney. Would first choice Enn Reitel have been as good a Del Boy as David Jason?
Jon Pertwee was ahead of Arthur Lowe in the casting for Captain Mainwairing. Do you reckon he'd would've done as good a job?
So, what about other 'classic' shows like Porridge, Yes Minster, Reggie Perrin, The Good Life etc etc?
