Not a bad Monday offering. The theme seems a little simplistic, but it's clean enough - symmetrical in position and in length of words. And the revealer, BODYDOUBLES (35A: Star stand-ins … or a hint to 17-, 25-, 48- and 58-Across) is kind of cute.
Got held up in the NE by mistaking "titles" for DEGs (44A: M.A. or M.B.A.: Abbr.) in 10A: Titles for attorneys: Abbr. (ESQS) (tried "llds"), but QUIETED (12D: Shushed) straightened me out. It's quite the Scrabble-y corner, eh? What with QUIETED and SQUEEZED (11D: Hugs tightly) side-by-side. Or should I say "côté à côté?"
In the "things I learned" department we have CAIRN (15A: ____ terrier (dog breed)), and the fact that the ANJOU is a "61A: Winter pear."
Frequent commenter and recent world-traveller Colum should be happy with his possibilities for Italy name-dropping today, with both GELATO (31A: Italian ice cream) and MILANO (45D: Certain Pepperidge Farm cookie), while Huygens will have to content himself with ONADATE, INSERT, and COMENOW.
