There is major evidence that the sequence with Mary Jo Barren in episode 1507 was filmed at least twice and pieced together. First of all, notice where the line of kids are as they go under the adults’ arms.
By the end of the shot shown above, the girl in the red and pink dress is nearly past Ms. Barren, however in the very next shot, she is not even under her arm yet.
A little later, Betty Aberlin is on right side of the mantle when they stop moving for a moment, then over on the far left, back on the right, and finally back towards the left, all “without moving.” Ms. Barren and the boy in the light blue shirt switch places as well.
Further into the visit, the girl in the red and pink dress (“Miss Nicky”) takes a turn “flying away,” followed by the boy in the yellow shirt (“Mr. Omar”)
After they sit down, the girl in the red suspenders is on the left and no one is between Mr. Rogers and the boy in the light blue shirt. In the next shot, the girl in the red suspenders has moved between Mr. Rogers and the boy in the light blue shirt.
Now it’s Mr. Rogers turn. Remember how the girl in the red and pink dress was on the left of the boy with the yellow shirt (above)… After Mr. Rogers “flies away,” the camera pans down revealing that she is now between Betty Aberlin and Ms. Barren.
Before, the shot ends, Ms. Barren again (even though the other children apparently haven’t had a turn) calls for “Mr. Omar” to fly away, but when the shot changes, it is definitely not Mr. Omar who “flies” by:
Finally, in the end it is not one of the girls who sits down (even though they obviously just passed the camera) but the boy in the yellow shirt. Some of the other children have moved again too. (It finishes with “Miss Sarah” flying away.)
Take a look at this episode for yourself by watching it via Amazon Video On-Demand.It’s strange how I never noticed this before, even though some of the changes are so obvious…
