"Grace Cullington is the oldest, no, sorry, was the oldest surviving (Chaplin co-star). I dedicate my award to her," the actor said as the woman was carried out of the room. "This is obviously a tragedy. She has upstaged me. But on the bright side, what a great way to go, giving an award to me. Thus, she'll probably make the Oscars' In Memoriam segment."
But it turns out "Cullington" was actually a stuntwoman. IMDb does not list a Grace Cullington among the cast of "City Lights."
