I looked a little into the Beatty biography on the net ( since I'm still sick and can't really go out and look at a copy ) and one reviewer says that in the book Beatty almost lived at Cielo (?) :
The infamous 1969 murders of actress Sharon Tate (wife of Roman Polanski) and others by the Charles Manson gang hit close to home for Warren Beatty. He had been approached to take over the lease from Polanski but decided against moving into the house. Had he not declined Warren Beatty might have been one of those murdered that tragic night.
So now not only Leslie Caron says she almost took residence at the place, but Beatty did also? I hope this is not the start of one of those "I coulda been there that night" senarios.
For the rest of the review go here:
Don't know how Beatty feels about this book but it doesn't appear to put him in the most positive light.
Here is an interview with the writer Peter Biskind:
