I believe the scene might have been from the movie. I remember it distinctly: the mother is in Laura’s bedroom and slowly the image of Bob is clear crouching in the bedroom.
In the U.S. broadcast, IIRC Sarah looks at the bed and there’s no one there, but in later episodes she remembers Bob crouching. I believe Lynch shot it for the European version (by contract, it had to have an ending that wrapped everything up, unlike the original U.S. version which lead in to the series), and since it was so scary, he imported it (and Bob, Mike, the Red Room, the Little Man From Another Place, and a shitload of other stuff from the European pilot) into the series.
For me the scariest moment is in the second season – Maddie is sitting on the floor in Donna’s living room when Bob walks in from the dining room, crawls over the couch, and starts advancing on her.
My memories of being wigged out while watching Twin Peaks are still so vivid that reading this thread, even before watching any clips, scared the crap out of me.
The oogiest part for me is the creamed corn kid from the movie.
Heh. I scared myself just thinking about the clip I posted, and then when I found it on YouTube I realized it was much, much scarier than I’d remembered.
I just finished watching the series and the movie on DVD, and as far as I remember they never specifically said what Bob was. Cooper and the others speculated about it in the last of the Laura Palmer-centric episodes (where the series should have ended, IMHO), and later on they find out he originally came from the Black Lodge (not that this really answers anything), but that’s about it. I always wondered if he was ever human to begin with, or always just an evil spirit. The one-armed man claimed he was Bob’s serial-killing partner in the past, but I was never sure if that meant Bob was a real person then, or that he was a spirit possessing someone else.
Actually, the whole Bob/one-armed man relationship was one of the most creepy/intriguing things about the series.
I don’t know what the hell Creamed Corn Kid was all about . . .
