Another 70's bright sun LA noir with a protagonist that mutters to himself in a way that should embarrass any self-respecting viewer is Save The Tiger starring Jack Lemmon. Not the critical darling that TLG is but it was Lemmon's personal favorite. With Jack Gilford

any self respecting viewer or reviewer?

just reading the comments below the long goodbye trailer i came upon this gem. 

Great movie. I was going to buy it on bluray this past weekend but Robot Jox was ten bucks cheaper.
