Here's a challenge...find your awards for the big 6 categories (nominees and winners) for as many years as you can using only those films which were eligible in their respective years.
You can find a link to every eligibility list Here
And yes I'm working on mine. It's an interesting premise, cause Ikiru is eligible in 1960...which is a crowded as fuck year as it is. Merely one of many weird little things with this.
