Goldberg gave herself a better review: "After seeing the final cut, she felt it was a substantial enough role to warrant best-actress consideration," Castle Rock president Martin Shafer told Daily Variety. So a letter was rushed out to Academy members upgrading her category.
Actually, the lines between "best" and "supporting" have never been very clear. Marlon Brando won a best-actor Oscar for The Godfather, and Anthony Hopkins did the same for Silence of the Lambs although their actual screen time was relatively short. Timothy Hutton won a supporting Oscar for Ordinary People, as did Tommy Lee Jones for The Fugitive, although many thought they should have been nominated as leads.
To further complicate things, a member can nominate one performance in both leading and supporting categories. Ballots are counted simultaneously in each category and an actor nominated for multiple categories gets pegged in the first one for which he or she gets the required number of votes.
Goldberg won a supporting-actress Oscar for the 1990 film, Ghost.
In another rave self-review, Madonna told a press conference in London today that she expected to be nominated for an Academy Award for her performance in Evita.
