. . . The Rocky Horror Picture Show, but did see Tim Curry once walking near the section of Sunset Boulevard known as "Dead Man's Curve". Curiously, there is no sidewalk on that section of Sunset, so he was literally walking on the asphalt. (The neighborhood is entirely residential, with ivy-covered walls on both sides.)
Memorable not only because it was Tim Curry, but also because I've never seen anyone else walking in that location, before or since! My guess is that his car broke down on a side street; this was before cell phones were common, so he would've been walking towards a phone booth on the other side of the 405 freeway to call for help.
