4 Poll Suggestions: Favorite Year in Cinema

Which year do you think has produced the best films? Each year is represented by its highest rated film at IMDb. Please vote your favorite YEAR of films and not necessarily the film that's listed. 

See the lists for your favorite year below: 
1. Favorite Year in Cinema (1920-40) : http://www.imdb.com/list/ls062370346/ 
2. Favorite Year in Cinema (1941-60) : http://www.imdb.com/list/ls062370970/ 
3. Favorite Year in Cinema (1961-80) : http://www.imdb.com/list/ls062375100/ 
4. Favorite Year in Cinema (1981-00) : http://www.imdb.com/list/ls062375698/ 

***A poll for the "Best Year of the 21st Century" has already been made.*** 

Depending on how these polls go, I will take maybe the top 4 or 5 voted years from each of the polls and make a culminating "Favorite Year of All-Time in Cinema"
