According to wikipedia she is and his son Crispian is a British film art director who has been nominated for three academy awards in the past for films such as Gladiator and Driving Miss Daisy.
I don't think theres much info out there about Mr Sallis' private life or his family. I think he must want to keep all that to himself. Fair enough, yeah? There is a photo on Google of Mr Sallis and his wife, must have been takes 20 years ago, though.
I think Peter's wife was at Pinewood with him in 1999, when they added the 'Summer Wine' plaque to their 'Hall of Fame'. But I can't say I remember hearing about her since. His autobiography was a bit if a disappointment as it told practically nothing about his life outside show business. I don't want a lot of gory details. but some info would have been nice.
I can understand your curiosity very well, but Rhi has got the point here. I can´t and I won´t talk about things Peter doesn´t talk about in public himself. But there is an article on the internet, so this is public, he is divorced. http://www.bucksfreepress.co.uk/news/1731472.print/
It's good of you to protect your friendship with Mr. Sallis, ****. And thanks
for the reference to the interview, although, I'm a little sad about his divorce,
but, I guess, it happens,eh?
