If you don't recognize the name, you'll recognize the face. I never really knew his name, but he played two small but memorable roles in two of my favorite films of all time.
I first saw him as Lt. Santino, Eddie's police contact in "Who Framed Roger Rabbit?"
Of course his most memorable role would be Imperial Admiral Motti, whose lack of faith Darth Vader found disturbing in "A New Hope."
This past Monday, Richard died suddenly at age 66. None of my sources mentioned cause of death, but I'm sure that information will be available soon. In any case, it doesn't matter. What matters is that he was a talented actor and he will be missed.
