The King of Comedy

Robert De Niro plays the ridiculously inept Rupert Rupkin, an aspiring comic who idolizes talk show host Jerry Langford (Jerry Lewis). Still living at home with his mother, Rupert spends his days trying to arrange a meeting with his hero. When he isn't doing that, he's at home talking to carboard cutouts in his makeshift television studio. After Rupert convinces Rita (Diahnne Abbot), a pretty bartender, that Langford has invited them to his house outside the city, the reality of the situation makes itself painfully apparent upon arriving at the star's front door. Trouble is, Rupert's too delusional to take the hint. He eventually hatches a plan with an equally obsessed fan, Masha (Sandra Berhard), to kidnap Langford in exchange for a chance to let him deliver his routine on the air.
