I LOVE classic films. Netflix instant watch is great for this though sometimes it's not the best quality. Google the 31 days of Oscars on TCM. They have a specific genere each day of favorite movies. Usually its the month of February.
My choices in no particular order:
Seven Brides for Seven Brothers
The Tammy Series(Tammy, Tammy and the Bachelor, Tammy and the Doctor)
Marilyn Monroe (Some Like It Hot, Gentlemen Prefer Blondes, How to Marry a Millionare, Seven Year Itch..)
Elvis Movies(Viva Las Vegas, Blue Hawaii, It Happened at the World's Fair, Girls! Girls! Girls!, Clambake....)
Elizabeth Taylor(Cat on a Hot Tin Roof, National Velvet, Father of the Bride)
Hello Dolly
Fiddler on the Roof
Guys and Dolls
Oklahoma!
South Pacific
The King and I
Kiss Me Kate
