"Nobody wants to pay twenty dollars to watch people living next to chemical waste! They can see that in New Jersey!"
Several weeks ago I came upon this collection of cameos by film directors, which included the recently departed Sydney Pollack's appearance in his film "Tootsie." It's inaccurate to refer to Pollack's role as agent George Fields as a cameo -- it was an important supporting role, and he and star Dustin Hoffman shared some of the film's most memorable scenes.
Pollack began his career as an actor and as the director cameo item notes, he had as many acting credits as he did directing credits. Among his other memorable acting roles, in my opinion, was his turn in the under-appreciated "Changing Lanes" as the amoral father-in-law of Ben Affleck's character, and his role as a man struggling with a midlife crisis in Woody Allen's "Husbands and Wives." And let's not forget his appearance in the final season of "The Sopranos." (See my summation of that episode here.)
Rest in peace.
