* Categories Vary: The number of categories for awards has changed over the years. Some categories have been added or removed, so the total number of nominations fluctuates.
* Multiple Nominations: A single film can receive multiple nominations across different categories.
* Data Availability: Not all historical data on nominations is easily accessible or perfectly compiled.
Instead of a precise number, you can find information on specific years or categories from the official Academy Awards website or film databases like IMDb.
