It must be a bit sad to win the Oscar but for everyone to think it's a blunder. It happens to Marisa Tomei because of one of the most widespread urban legends in Hollywood.
The legend: Jack Palance, who had a long history of alcoholism, was drunk when he read out the name of the Best Supporting Actress Oscar winner at the 1993 ceremony. Hence, he mistakenly said Marisa's name Tomei. The Academy of Cinematographic Arts and Sciences never wanted to undo the wrong so as not to be at the height of the bitumen. Other variants of the story suggest that the interpreter had not drunk, but had vision problems, and it is also said that he could have bet with his friends that he was going to say the name he wanted.
Empirical facts: Marisa Tomei was not considered the favorite at all. It is noticeable that she got a huge surprise when she heard her name, and even she was about to fall when she went up to collect the award.
What is true? It is not credible that it really happened, since on each side of the Oscar stage a representative of the PricewaterhouseCoopers audit awaits, pending any ruling, as seen in the famous wrong delivery of 2017, when Faye Dunaway and Warren Beatty declared the winner to La La Land to the detriment of Moonlight. The story has a very simple explanation. Marisa Tomei was up against Judy Davis for Husbands and Wives, Joan Plowright for An Enchanted April, Vanessa Redgrave for Howards End, and Miranda Richardson for Hurt. All of them have much more prestige as actresses than poor Tomei, who according to any analyst didn't have the slightest chance of succeeding.
And predictably... she had been stripped of all of her Oscars Race awards! Hence, gossips began to attribute her success to some kind of slip. With great effort, the interpreter has retaliated in a certain way, since she has later achieved two other candidacies, for En la habitación and El luchador.
