Okay, I just love this theme. Take a 15-letter word and reparse it into three completely unrelated words, clue wackily, and there you are. I had no idea what was going on for a very long time, working my way around the theme answers in dribs and drabs. Then I had __MP__A__TALLY at 36A: Noodle count in one of Arizona's largest cities? I guessed the Tempe part of it, but put in "pasta" in the middle for TEMPEpAstaTALLY. That made no sense. Was it some sort of pun?
So then I figured out RECONSIDERATION. That's awesome: recon / side / ration, such excellent reimagining of that word, especially taking the two syllable middle and turning it into one syllable. That finally broke the theme, and I changed the middle to TEMPERAMENTALLY. Finally, came NONCOMMUNICABLE (noncom / muni / cable), which I found the least clever of the three.
But that's not all. Look at all of those long down answers! Four 8-letter answers, and four 11-letter answers. It took me forever to understand 9D: Faux bronze (SPRAYTAN) - hah! I also really enjoyed 24D: Did a tour after joining up? (HONEYMOONED) - way to disguise the answer. And how about 6D - Clark Kent's newspaper the DAILYPLANET. I got that off of IDRIS Elba (outstanding actor).
There are a ton of interesting and fun clues: the pair of old-time advertisements in ELLA Fitzgerald's Memorex ad and Willie the Penguin's KOOLS spot. Two that got me were 40A: Pounds, for example (MONEY - no final S here!) and 27D: Biblical mount (CAMEL) - not Sinai (note the lack of a capital M in the clue). How about 50D: Pen name (BIC)? Tough!
ROSHAMBO was the site of my error: I had put PINTo in for PINTA, and didn't know the cross at all. Apparently, that's a West Coast name for the game.
I had a lot of fun with this puzzle.
