Yes, this is a goulish question.

I was wondering the same thing. Natalie Wood died in Nov 1981, so Hart to Hart was in its 3rd season at that point, at the peak of its popularity.

According to Robert Wagner's book, they had just finished filming in Hawaii when they took their fateful trip to Catalina. Episodes 14 and 15 of season 3 were shot in HI. If they shoot them in order, episode 16 would be the first episode shot after Natalie Wood's death.

If Episode 16 is, in fact, the first one, then this is pretty interesting to me. "Blue & Broken Harted" is the episode --> http://www.imdb.com/title/tt0597210/. In my review, I don't make any mention of art imitating life or emotion beyond the 4th wall, and I do look for that stuff. I do recall a very well done, emotional fight they'd staged as part of their investigating, but the fight, itself, was really emotional, even if they were faking it. Emotion feeds off emotion, and so some of RJs may have been feeding his performance, but this is not an ep that made obvious that Natalie had just died. Knowing this, however, I'm going to go back and watch it.

I've often wondered this, myself. If the above poster is correct, it is interesting to note the title of this episode... "Blue and Broken-Harted". How sad for the both of them. All these years later and I still can't believe the tradgedies they both faced at the exact same time. Just awful :(

The episode, under production at the time of Natalie Woods death, was Hart of Diamonds. I have a newspaper clip of RJ Wagner, returning to work on the set, with Stephanie Powers and the actress, that played Lily Von Borg, the woman who was using hypnosis, on Jennifer, to become a jewelry thief!
