We've been working through the Nero Wolfe TV series that aired some years ago; we're getting the DVDs from Netflix.
If you didn't catch this when it aired, it's worth a look even if you're not a fan of Wolfe.
These were superbly (and likely expensively) produced by the "A&E" network back then, and stars the late Maury Chaykin as Wolfe.. He chews the scenery wonderfully.
Timothy Hutton does his leg-man, Archie Goodwin, to a turn, and the ensemble cast is great... They do a kind of repertory turn with the same actors in different roles.
Yes, and the wonderful thing is they kept much of the dialog from the books.
I've found this to be rare in screen adaptations.
