Life and active members of the Academy of Motion Picture Arts and Sciences vote on eligible entries in most categories. Entries with the most votes become official nominations. Academy members then cast final votes, and two or three people representing a third party tabulate the votes.
AMPAS has specific guidelines to determine eligibility for Oscar consideration. Each category has its own unique guidelines. Any entry in any category is a potential Oscar nominee and winner, providing the entry fulfills the guidelines.
An eligible feature film must be at least 40 minutes in length and exhibited using 35-millimeter or 70-millimeter film in a Los Angeles County venue for at least seven days during the same year of contention. In some categories, members of corresponding branches typically receive and cast nominations, so actors nominate actors and directors nominate directors. All active and life Academy members nominate and cast final votes for Best Picture.
Members receive reminder lists of potential nominees around voting times. Each production may account for up to 10 female and male actors for Best Actor consideration. Actors who are life and active members vote for five acting achievements in order of preference and again for a single nominee during the final voting process. The nominee with the most votes receives the Oscar. PricewaterhouseCoopers, or PwC, tabulates all ballots, as of 2015.
This Oscar voting process applies generally to most categories except the Animated Feature Film and Foreign Language Film categories, which entail the Academy president selecting a special committee that reviews the entries and votes privately.
