It would be hypocritical of me to take issue with anything in questionable taste, seeing that I invented bad taste in films… No. There’s no such thing as too far. If it works it’s funny, if it doesn’t work it’s too far, it’s stupid. Really there’s no such thing as “too far.” You’re joining the politically correct when you use words like “too far.” You don’t want to join the army of politically correct.
Reordered list because Mel Brooks is just too good to be #3 — and, because I adore Anne Bancroft.
