Ok, before the hints, an admission that this one killed me.  I don’t think it’s just cause I started late in the evening.  I just don’t know who the “Monkey launched in 1958”, what Mercutio cried repeatedly, who was in Unfaithful or the name of the announcer in, what was it, Let’s Make a Deal?  So I have to admit, I went into a pure guess & check mode with those four squares.   Maybe because folks can google answers so easily, it does feel to me that Friday and Saturday puzzles are getting more combo obscure answers.   So I, the hint giver, must cry, “Gimme a hint!”

Ok, finally done, though with far too many wrong guesses before the denouement. Painful after all these years.  Oh, well.
