Come Back, Little Sheba

Review above, from 2020 has to be the strangest thing I ever read. I had to look at twice to make sure I got all the words right. The reviewer mentions that (s)he got the DVD of Laurence Olivier set. (that would be 2006 set that several of his made for TV plays), but "The subsequent deaths of Olivier, Woodward and then Carrie Fisher put me off for reasons of sadness"

What alternate reality has this been written in?? Laurence Olivier died in 1989, more than 30 years before that review, and more than 15 years prior to dvd set release! Did he only found out about Sir Larry's death 30 years after the fact, or was he still mourning Larry 30 years later??

And Joanne Woodward is still alive (and was in 2020). Did he decide to mourn her future death??
