“If he [Stevens] had been prepared to come back for maybe two or three episodes in a series, that would be different. Then we could have had a foreign posting or invented a career that would have made it possible for him to be away.
“Otherwise we would have had to make this tremendously successful love affair between Mary and Matthew unhappy, which I didn’t feel would be believable.
“For them to then separate and Matthew never set eyes on his son again would not be believable either.
“So we didn’t really have any option. By him dying, their love can remain in tact.”
If the series were going to run on an on, I would have prefered that they replace Matthew, but I suspect others are right that it will only go through 4 or maybe 5.....but you never know....How many James Bonds were there? Phantoms?
