Continuity mistake: The first ambassador is given 3 Polaroids; he drops one on the road and enters the car where he now has the same 3 photos again. Then in the close-up, he only has two; the one he dropped is missing, but a shot later he's got all 3 again.
Continuity mistake: By the car, the first ambassador holds the three polaroids in a fan-like manner, but a shot later they're stacked. This swaps back and forth.

Deliberate mistake: In order to knock down Ted at the laundry place, Diana opens a bag filled with clothes that are supposed to fall on him. The bag is too low plus the actor is away from the bag, so when she opens the bag he crouches, then grabs the clothes and pours them on top of him and falls down. It's all very lame.

Answer: The first actress, Cloris Leachman appeared in the TV movie which ended up being the pilot for the series. At the time, Leachman was already starring in her own TV series "Phyllis" (a spin off her role in "The Mary Tyler Moore Show"). This was actually the 2nd TV movie meant to be a pilot and the first one wasn't picked up. It's likely she thought the show would be picked up. After season 1, in which Carolyn Jones played the role, ABC was slow to make a decision to pick up the series for season 2 and CBS picked up the series. When CBS picked up the series, they changed the time setting of the show and replaced all the actors, with the exception of Carter and Waggoner (with Waggoner playing a different role technically), resulting in Beatrice Straight being cast.
