David Janssen, as always, gives a credible, wonderful performance in "An Apple a Day." Even with a less-than-inspired script, he's able to rise above. In addition, Sheree North as Marianne Adams is really quite good. And Arthur O'Connell as Josephus is also pretty good in his role. It's just all kind of slow, with not much happening. But there are a few specific scenes I like in this episode, and they all come in quick succession.
There's a scene with Marianne and Kimble that's done very well - Marianne pours a scotch for Kimble after a couple of days of only honey-based drinks and foods. She's trying to soften him up.
Very soon after, Mrs. Crandall, the older woman played by the actress Amzie Strickland, is brought to the house unconscious. The director, Ralph Senensky, tells a story years later in his blog that during rehearsals, Amzie said to David Janssen, "Dr. Kimble, how about a little mouth to mouth resuscitation?" Now, whenever I think about this episode and that scene in particular, I have to laugh.
Later, Kimble finds the bottle of honey-based cough syrup that Mrs. Crandall had been taking and, in a fit of frustration, smashes it. It was good to see. Kimble's always so tightly wound, so in control, careful, and holding tight to his emotions that it was good to see him finally let go.
The ending with Josephus's niece Sharon (Kim Darby) becoming very ill is weird. There's no real explanation for it, except that it serves to wrap up the storyline of what happens to Josephus's medical practice before Kimble goes off to his next destination.
So, this isn't one of the great episodes, but I do like some parts of it very much.
