Great show! Wally is such a terrific guest, so humble and down-to-earth for someone so talented.
However, I do agree with BWH on a couple of his points. I liked Astin's take on the character. Even though it doesn't measure up to Gorshin's overall, he had his moments. There is something threatening about him.
And as BatWinged Hornet alluded to, comparing Shatner's post-Trek career arc to Adam's post-Batman arc isn't quite valid. Yes, there were lulls, and some rough times, but Shatner worked very steadily, albeit as guest baddies of the week and in a lot of forgettable TV movies and quickly canceled series. But he worked, nonetheless. And, to be fair, same for Nimoy. If you check his Wikipedia page, and not only imdb, you'll find he did a lot of legitimate theater after Trek, both on Broadway and in, err, Londinium.
Some more housekeeping--Cliff Robertson won the Oscar AFTER Batman, not before.
Charly was released in June 1968, post-Shame. One can make the argument that Robertson was the biggest star
at the time to appear on the show, with perhaps, as much of a pain on the set in the rear as she was, Shelley Winters a close second.
I also would add, and you all know I am far from a Dozier apologist, that Frank's salary demands in season 2 put him in a tough position. If he raised Gorshin from $3,500 to $5K per arc, the equivalent today of going from $27,710 to $39,585 per

I also believe Dozier deserves credit for banking, pun intended, on Frank in the pilot in the first place. Burgess Meredith would have been the easy and safe choice for the pilot and premiere. But Frank proved to be the wild card that got the show immediate buzz, and the rest is history.
