The Razor's Edge--1946 version--much much better--more true to the book.

Good dialog, good conflict.

Larry younger, played by very good looking Tyrone Power.

Bill Murray was too old and too cynical and a bit thuggish.

I much prefer this one.

The fashions and the manner of the times makes Larry especially look older and more polished

whereas he never really fit into society.

Yes, a remake with Larry always looking a little disheveled and non-comformist--for e.g. his clothes were worn and he lived very simply--he needed a shave and a haircut and needed a cleanup before he was presentable--and he was always a bit uncomfortable-- and liked to leave and arrive abruptly, always canny about his address and phone number.

He was a loner.
