There are simply too many good movies to list the "greatest" ever or even all of my favorites ... here, though, are a few very good movies that come quickly to mind whose titles I didn't see above ... I'd watch any of these anytime ...
"The Lion In Winter"
"Giant"
"Slap Shot"
"The Birds"
"North By Northwest"
"A Man For All Seasons"
"The Sting"
"The Hustler"
and ... my all-time favorite movie that no one's ever seen ... except those of you who followed the recommendation I made when this subject came up once or twice before, most recently a year or maybe two ago ...
"A Big Hand For The Little Lady"
starring, Henry Fonda, Joanne Woodward, Jason Robards, Paul Ford, Charles Bickford, Burgess Meredith, Kevin McCarthy and Robert Middleton
