Wait, I'm reading your "solution" now... but I didn't think it was supposed to be Terry Crews!? There really is a Jervy Cruz! haha (https://en.wikipedia.org/wiki/Jervy_Cruz)
Reveal: As hinted at in the title, there are names in the grid that become different names by changing one letter- 1A becomes NOAM by replacing the H with M, 21A = DANNY, 39A = MARTY, 42A = TERRY, 57A = WILLY, 72A = NORA. There are clues in the down answers that point to which letter should be switched- NOAM 7D + 44D (I know, I know. I’m sorry!) DANNY 50D, MARTY 52D, TERRY 28D, WILLY 55D, NORA 20D. The replacement letters spell MARTIN. You may have noticed in the meta prompt that the letters T & V in the word TeleVision are capitalized. This was my attempt to nudge you to replace the T with a V. Hence, MARTIN becomes MARVIN. The candy bar reference hopefully pointed you to MARS, culminating in the meta answer: Marvin the Martian.
