The late, great Roy Scheider appeared with Welles in IN OUR HANDS, a 1984 documentary about an anti-nuclear protest in New York's Central Park. I've never seen IN OUR HANDS, but somehow doubt that Scheider and Welles shared any screen time. Still, I was surprised to discover they actually co-starred in a film together – albeit an obscure documentary.
One of Scheider's final roles was as a bargaining serial killer on Death Row in ENDGAME, last year's remarkable season finale of LAW AND ORDER: CRIMINAL INTENT. As the manipulative Mark Ford Brady, Scheider toys with the increasingly unstable Detective Robert Goren, played by Vincent D'Onofrio, who starred as Welles in ED WOOD (1994) and in the 2005 short FIVE MINUTES, MR. WELLES.
