The actor that played Bob, Frank Silva, sadly died years ago.
Potential Spoilers ahead…
True story - Silva wasn’t originally in the show, but was a part of the crew. Lynch added him to the show spontaneously, as a result of picturing him trapped inside of Laura’s room. His appearance in the show mirrored his real life attire. And this…is the difference between Twin Peaks and the countless imitators it’s influenced.
