Mission Impossible:............................

............picking the twenty best films of a particular decade.  Here is one list trying to capture the 1960's.  It is a good list, but to show just how difficult the job is, here is another list of twenty:

It's A Mad, Mad, Mad, Mad World
The Great Escape
Zorba The Greek
My Fair Lady 
Days Of Wine And Roses
Bullitt
The Russians Are Coming, The Russians Are Coming
Easy Rider
One Hundred And One Dalmatians
Where Eagles Dare
In The Heat Of The Night
The Pink Panther
Cat Ballou
The Longest Day
Midnight Cowboy
The Guns of Navarone
Z
Funny Girl
The Producers
Georgy Girl

Left off the lists are James Bond, the three Beatle movies, and a host of mighty fine musicals.  Clint  Eastwood, Frank Sinatra, and John Wayne are vastly under represented.   Truly an impossible mission.
