correct about everything
If we limit it from May to September, 1982 seems to be pretty tough to beat. Just look at this stuff right here (picking the best here, so not the full release list):
I included The Beastmaster for all the kids, wink wink nudge nudge.
The Thing and Blade Runner released on the same day? Already the best summer. Very balanced, too. The whole year was also very strong since outside that list there were Porky's, First Blood, 48 Hours, Sophie's Choice, My Favourite Year, The Dark Crystal, Tootsie, Gandhi and The Verdict. 48 Hours, The Verdict and Sophie's Choice were also released on the same day, so that's probably pretty high on an all time stacked release days-list.May 14
