Was 'Rainy Day' the first filmed episode?
As every die-hard fan knows, in the first season, they would shoot scenes completely randomly. For example, they would shoot scenes from one episode, then shoot scenes from another, then back to shooting more scenes from the same episode, and so on, and so on. It wasn't until season 2, that they actually moved on to filming one episode entirely, before moving on to the next, like in pretty much every other filmed series.
In "Rainy Day", the first act at least, Pee-wee sounds different, the original Globey doesn't have his white neck yet, and Pee-wee opens the picturephone drape right, rather than to the left, among other differences.
Thoughts?
