Rebecca

Two versions of Daphne du Maurier's Rebecca. The first is the 1979 BBC production which was also one of the first programs to be featured on the new PBS Mystery! series in the U.S..
It featured Jeremy Brett (of Sherlock Holmes fame) and Anna Massey, his first wife, also had a role. http://en.wikipedia.org/wiki/Rebecca_%28novel%29
Carlton Television, in association with WGBH, produced another version in 1997 that was also presented by PBS Masterpiece Theatre in the U.S. This version starred Emilia Fox.
And if you just can't get enough of Rebecca, the 1940 Alfred Hitchcock film is found on Hitchcock Disc 5. http://en.wikipedia.org/wiki/Rebecca_%28film%29
