Yeah I saw and enjoyed Marathon Man, it would be one of my "bubbling under" films. Found it a little more captivating than some of Schlessinger's other films (particularly the self important Sunday, Bloody Sunday). Speaking of the two, I would still say Midnight Cowboy was his finest hour.

The Death of a Salesman was a made for TV stage play directed by Volker Schlondorff (@#%$ the spelling), and he played Willy Lohman, quite well to boot.
