UNMENTIONALBES
· The Academy got a scare in mid-January when it got word that phony nominating ballots were circulating on college campuses in New York, Los Angeles, San Francisco and Pittsburgh. Price, Waterhouse threw out incorrectly labeled ballots, and the nominating proceeded without a hitch.
· The Ambassador Hotel had provided parking service in previous years. Not so with Grauman's Chinese. So arriving guests were forced to fend for themselves and a steady stream of people entered the theater during the first half of the ceremony.
· Ten tiers of seats rose up at the rear of the stage for the soldiers and sailors invited to attend the show. Their arrival got the most sustained applause of the night but they spent the rest of the evening watching participants' backs.
· The Song of Bernadette lost Best Screenplay to Casablanca, a film that was rewritten daily on the set during filming.
· Studio chief Jack Warner accepted the Best Picture Oscar®, not the film's producer, Hal Wallis. Insiders cited this as a major cause for Wallis's move to Paramount later in the year after two decades at Warners.
· Losers Jean Arthur and Joan Fontaine and their husbands immediately took off for a bar on Rodeo Drive.
· Loser Ingrid Bergman, who had a lock on Best Actress until The Song of Bernadette came along, ran backstage to congratulate friend Jennifer Jones, who was receiving felicitations not only for her Oscar® but for her 25th birthday. The winner told Bergman, "I apologize, Ingrid. You should have won." "No, Jennifer, your Bernadette was better than my Maria."
· A few days after the ceremony, the Screen Directors Guild announced that its members were seriously considering leaving the Academy because their Award was relegated to the first part of the program, before the radio broadcast began.
· Daily Variety pointed out that Bernadette's "prestige" campaign blew up in its face: at Oscar® time, Bernadette was still in limited release at advanced ticket prices, which meant that those with the bulk of the voting power -- the extras -- had not yet been able to afford to go to the movie. A poll of voting extras showed that only 25% had seen Bernadette, whereas nearly all of them had seen -- and voted for -- Casablanca.
