I agree completely with all of your praise for the late Mr. Leonard. While I wasn't the biggest fan of his on the planet (I think an old partner of mine was that), I enjoyed his work and I always appreciated his talent and abilities as a writer in several areas.
I chime in here not to hijack this thread (in fact, I waited until its activity appeared to have tapered off) but because I assumed that most of you who commented earlier might also be interested to know that a journeyman film and (early) TV director who died on the same day as Mr. Leonard, might also have been someone whose work you respected.
Ted Post passed away on August 20th 2013 at the age of 95.
Mr. Post is nowhere near as well known (and to be honest probably not anywhere near as talented) as such contemporaries of his as John Sturges (now dead for over 20 years) and John Frankenheimer (dead for over 10) but if you have contributed to this site, then more than likely, you have also seen his work.
People never watched the credits much when he occasionally held the reins on such television shows as Medic (with Richard Boone), gun enthusiast Erle Stanley Gardner's Perry Mason, Richard Diamond (with a pre-Fugitive David Janssen), The Rifleman (that featured the talents of just about every action writer and director of the period), Sam Peckinpah's own The Westerner (with Brian Keith), Wagon Train, The Virginian, Gunsmoke, (prophetically) Rawhide, Combat, Boris Karloff's Thriller, Rod Serling's Twilight Zone, and more others than I can remember.
And while he made some pretty schlocky Made-for-TV movies in the 70's and 80's when such things were in vogue (hey, a guy's gotta eat), he also directed Clint Eastwood's return to the American Western: Hang 'Em High in 1968 (a film that was also the first release from Eastwood's long running Malpaso Production Company), Eastwood's return to Dirty Harry in Magnum Force in 1973 (although it probably also ended the two's friendship), and the rarely seen but very worth seeing Go Tell The Spartans with Burt Lancaster in 1978.
Just thought you might like to know.
