An epic that broke up two marriages, nearly killed a film studio, and reigned as the most expensive film ever made for 30-plus years. A thriller that made flocks of birds a fearsome sight for an entire generation.
Throw in the last great "Star Wars" film (before prequels and Jar Jar Binks dimmed the franchise), a few holiday classics (including an unlikely "holiday"), World War II tales of heroism, and pop-culture peaks and a Valley Girl, and you have a 2013 packed with notable movie anniversaries.
Other cinematic greats — and not-so-great but definitely memorable — will be observing their 20-, 25-, 30- and 50-year milestones in 2013. Start chilling the bubbly and consider what's coming up the anniversary queue.
