Abraham's relatively low-profile film career subsequent to his Academy Award has been widely considered an example of the Oscar Jinx; according to film critic Leonard Maltin, professional failure following an early success is referred to in Hollywood circles as the "F. Murray Abraham syndrome". Abraham rejects this notion and once told an interviewer:
"The Oscar is the single most important event of my career. I have dined with kings, shared equal billing with my idols, lectured at Harvard and Columbia. If this is a jinx, I'll take two."
In the same interview, Abraham said:
"Even though I won the Oscar, I can still take the subway in New York, and nobody recognizes me. Some actors might find that disconcerting, but I find it refreshing."
