Tragic that he died so young and so suddenly. My thoughts are with his family. I haven't seen most of his films, but enjoyed
Breakfast Club as an in-flight movie (despite being fairly standard school story fare, it succeeds in mocking stereotypes and underscoring the need to look beneath the surface, rather than rely on superficial impressions).
Planes, Trains, and Automobiles and
Uncle Buck follow the same general trend as comedy films with a heart.
I've just checked Wiki and it turns out that his writing credits were even more extensive, including teen classics like
Pretty in Pink and the first
Beethoven film - throwbacks, perhaps, to a more innocent era, but films my generation grew up with.
He'll be missed.
