Wow, there has been a rash of 1980s remakes in the last couple of years. In my opinion the John Hughes movies and Back to the Future Trilogy would be too iconic to remake. Only time will tell.
Arthur (2010)
Clash of the Titans (2009)
Conan the Barbarian (2011)
Fame (2008)
Footloose (2011)
Fright Night (2010)
The Karate Kid (2010)
Red Dawn (2010)
The Thing (2011)
And a list of 1970s and 1980s horror remakes:
A Nightmare on Elm Street (2010)
Amityville Horror (2005)
Friday the 13th (2009)
Halloween (2007)
My Bloody Valentine (2008)
Prom Night (2008)
Stepfather (2009)
Texas Chainsaw Massacre (2003)
