Other mistake: Rupert almost got to the end of the cue cards when he flips too quickly the one saying "Alive", partially hidden behind another he is holding in his hand, showing the one saying "again" too early. So Jerry asks him to go back. And he does, only to bring then from behind "again." There is a small bit when De Niro is off-camera, but for this sequence to go as shown, he would have slipped to the bottom/the back of the pile the "again" card that was already at the top and then put in its place one of the two he had already in hand, the correct one, "alive." The fact that "again", that was at the top of the pile, is pulled from the bottom instead, makes no sense. (01:08:50)

Directed by: Martin Scorsese
Starring: Robert De Niro, Jerry Lewis, Sandra Bernhard, Diahnne Abbott
Continuity mistake: When De Niro's character gets in the limousine with Lewis' character he has a hurt hand. He wraps it with a handkerchief. As the scene progresses the handkerchief disappears and reappears depending on the camera angle. (00:07:15)
Rupert Pupkin: The more scribbled the name, the bigger the fame.
