I could watch these movies all day, any day:
Planes, Trains & Automobiles
The Breakfast Club
She's Having a Baby
National Lampoon's Christmas Vacation
I could watch them. And watch them. And rewatch them.
I also enjoy watching some of the movies he produced:
The Great Outdoors
Home Alone 2
My thanks and respect to the man who brought us these movies: John Hughes. RIP. His genius and comedic acumen will be missed.
