Born Dorothy Nicolette Pettigrew in London, she made her screen debut in the 1920 film "Wuthering Heights" and appeared in several British films of the early 1920s including "The Prodigal Son".  Following the Slump of 1924, in which the number of British films released sharply declined, she moved to Germany.  Her film career ended with the introduction of sound.  She was married to the Dutch actor Ernst Winar.

The Chris Farley Show was a sketch from the American comedy TV series "Saturday Night Live", which involved comic actor Chris Farley, as a parody of himself, interviewing various celebrities.  Rather than ask his guest questions that had any popular significance, or allow his guest to plug a current project, he would invariably act nervously, and simply describe scenes from a film in which the guest actor appeared (or occasionally films that had nothing to do with the guest).  After asking the performer whether he remembered this particular event, Farley would relate, "That was awesome."  Other times, he would ask questions that were of little relevance, or made no sense at all.  Invariably, he would say something he regretted and would smack his head and call himself an idiot.  The skit accentuated Farley's shyness for comic effect.
