My favorite 80s movies:

Back to the Future Trilogy
The Empire Strikes Back
Return of the Jedi
Vacation
High School USA
The Breakfast Club
Ferris Bueller's Day Off
Uncle Buck
Christmas Vacation
Fast Times at Ridgemont High
Spaceballs

Stand by Me is also a good movie. I also like the Revenge of the Nerds movies.

Back to the Future
High School USA
Light of Day
The Secret of My Success
Bright Lights Big City (seeing MJF as a coke addict was a bit disturbing, though)
The Labyrinth
ET (haven't watched that in ages)
On Our Own (I think that's from the '80s)
Vice Versa

I'm sure there's more, but I can't remember off-hand.

* I don't really like Class of 1984 or Casualities of War that much, even though both have Michael J Fox in it. Both were too violent for me.

Aren't the first five of them Michael J. Fox movies?

Yeah, they are. That's why they're on my list of favourites.
