I'd recommend two old foreign films you might not have seen:
"The Umbrellas of Cherbourg"
French--Stars a very young Catherine Deneuve.Has an absolutely exquisite score by Michel LeGrande.The entire movie is sung, rather than spoken.
And, if you want a sad (heartbreaking) love story --guaranteed to give you a good cry:
"Elvira Madigan"
Danish film.This one has been running on some of the cable channels during the past few weeks.So, you might catch it on TV.
And I love:
"Love Story" (Ali McGraw and Ryan O'Neal).
"Love With A Proper Stranger" (Natalie Wood and Steve McQueen).
"The Way We Were" (Barbra Streisand and Robert Redford).
"The Bridges of Madison County"(Meryl Streep and Clint Eastwood).
"An Officer and a Gentleman" (Debra Winger and Richard Gere)
"The French Lieutenant's Woman" (Meryl Streep and Jeremy Irons).
"Now Voyager" (Bette Davis and Paul Henreid).
And almost any old movie with Charles Boyer or Leslie Howard--particularly if it also starred Ingrid Bergman.
"Intermezzo" with Howard and Bergman is just great.
