OK.  The minor cast who supported me as I was starring in my own movie of my life.  Not necessarily in order of appearance.  
Christopher Isherwood. There's a new biography about him just published this month, and that's how I happened to think of him, though I'd read a few of his books when I was much younger.  He was a writer in Europe and then a screenwriter in Hollywood before I met him.  He had a casual walk-on role in my life, even for a visiting writer.  We actually met once.  He wore shocking pink socks.  We didn't seem to hit it off, though he politely exchanged a bit about Japonisme and I a little something about samurai armor.  When he was introduced at a gala assembly for students, they used my joke.
"Christopher Isherwood ... you might know him from the Broadway musical made about his life."
