Damon plays on SALAD DAYS (a term from Shakespeare), using four men with last names doubling as types of salads. SID CAESAR I knew off the top. TOM GREEN vaguely stirred a memory (he's the guy that used to star in "The Tom Green Show," not surprisingly).
ORSON BEAN apparently has done a huge body of work both in film and TV.
I probably should know LEE J COBB, as he's had many major movie roles. More importantly, he comes up not infrequently in crosswords as LEE J — not a lot of options when you need a four-letter entry ending in J!
Interesting choice to cram the themers together toward the middle of the puzzle — usually the first and last themers go into rows 3 and 13 to maximize spacing. But sometimes, squeezing pairs together can make the construction easier. Today, it's like Damon only has to work with three (albeit long) themers.
It does allow for a novel grid layout, including a lot of 6-letter entries. DENALI, AW GEEZ, PAYPAL, I GUESS, PAELLA are not only great words/phrases but since most crosswords don't feature many 6-letter entries, these feel nice and fresh.
I wasn't so thrilled about some of the shorter fill, though. I probably wouldn't have minded that central RVER / SERE / ONT section if there hadn't been more AGT, ESAS, NEC, USD gluey bits elsewhere. Tough, working around a central 9-letter theme answer.
EWERS and EPEE don't bother me much, as they're real-life things, but I have heard grumbles about these. (My wife, who's much, much smarter than me, dislikes EWERS, as she knows the word only from crosswords.)
Puzzles featuring proper names — especially full names — can feel like a trivia contest. So to get some AMATI, BLY, DEY, MACAU, NGAIO in addition to the themers felt like a lot of names in one puzzle.
But all in all, some nice thematic finds, covering a range of salads. And quite a lot of great bonus fill — some great 7s in MANSMAN, MIC DROP, MOOCHER, HOLY ARK — albeit, with prices to pay for them.
