For uplifting, light films, don't watch any movie from these directors:
Sam Peckingpah
Erich Von Stroheim
Wes Craven
David Cronenberg
Bernardo Bertolucci
ANY is a strong word, and really doesn't fit here.
First of all, it's not "pecking"pah, it's Peckinpah. Second of all, I think both
The Ballad of Cable Hogue and
Junior Bonner are fine entertainments that are just about completely devoid of the kind of brutality Sam is most often identified with, instead infused with genuine elegiac atmospheres.
As for Wes Craven, he directed a passion project called
Music of the Heart which is the very definition of "uplifting", a based-on-a-true-story drama starring Meryl Streep (who was Oscar-nominated) as a dedicated violin teacher.
Bertolucci's
Stealing Beauty has some serious themes, but is by far the lightest in his filmography, a dramatic tone poem about the intertwining of love and sex that launched Liv Tyler's career.
But that's the danger of using a word like "any".
