This is similar to the thread for noticing new things while rewatching TMM, because in rewatching FTB, there's a few minor things I hadn't noticed before until recently, especially with the 25th anniversary edition DVD:
Just to name a few.
- In the long shot as we see, from Ernie and Bert's perspective, moving in on Big Bird, there are a couple of crew members standing in the field next to Big Bird, as well as a couple of parked cars (really only see this in widescreen).
- In certain shots during "Upside Down World", half of Ernie's tongue comes loose from his mouth.
- In "Ain't No Road Too Long" (again, this is only in widescreen), you can see two really big rods coming out of Grover as he makes a dive out of frame.
Just to name a few.
