There's nothing on Rall in the new Katz.  To find out if he's still
alive, you might try looking through the indexed "Variety Obituaries,"
which many university and public libraries carry.  (He was probably still
alive as late as 1991, when the very reliable "Motion Picture Players'
Credits" by Jeffrey Oliviero didn't list a date of death for him.)  You
might also call the Screen Actors Guild representative line (at (213)
549-6737) and ask if he has an agent or rep. you can contact.  Happy hunting!
