The trio pose as von Hammersmark's Italian friends, carrying suicide bombs. When Hans Landa sees the group, he asks Donny's name, which he tells it in a very stereotypical fashion. It should be noted that while Donny's Italian is supposedly not as good as Aldo's, he actually tried to disguise his native accent, unlike Aldo who said his lines in a very thick Appalachian accent. When Bridget von Hammersmark tries to lose Landa by saying they need to get to their seats, Landa demands Donny and Omar's tickets, 0023 and 0024, and sends the two in the cinema auditorium, leaving Bridget and Aldo with him. In the auditorium, Donny and Omar look around seeing Goebbels and Francesca in one opera box, and Hermann Göring, Emil Jannings and Martin Bormann in the other opera box. When they reach their row, they discover their places are in the middle of German military. After an awkward look, they excuse themselves in Italian, and go for their places.

As the duo wait for Hitler to arrive with their bombs wrapped around their ankles, Landa kills Bridget, and has Aldo and Utivich transported to a closed bar, where Landa negotiates his surrender in exchange for allowing Operation Kino to continue. During the screening of the film, Donny leaves his place to see if Hitler has arrived. As he looks at his opera box door entrance, guarded by two soldiers, he suddenly sees the Führer himself exiting the door and asking one of the guards for some gum. Thrilled, Donny returns to the auditorium and calls Omar to come with him. The duo enter the bathroom, where they plan to kill the guards, take their guns and kill Hitler. He tells Omar after he kills one of the guards, he has 30 ft. (9 m) to kill the other one. Donny disguises himself as a waiter, concealing his OSS Glove pistol under a towel he cut with a concealed knife. Just as he shoots one of the guards in the head with the concealed gun, Omar jumps in and kills the other. After Marcel ignites the nitrate film pile, Donny and Omar burst into Hitler's box, emptying two MP40 magazines on Hitler and Goebbels, with Omar doing the same to Francesca. They then proceed to shoot at the audience below, not knowing that the doors were locked by Marcel. Donny empties his last magazine in Hitler's face, just in time before the bombs go off killing everybody in the cinema.
