The man who wanted to be loved by strangers
Rupert Pupkin is one of Robert De Niro’s most disturbing creations, and also one of his funniest. Rupert is an aspiring stand-up comedian in New York who believes, with complete sincerity, that he is on the verge of fame. He waits outside a television studio, he rehearses jokes in his bedroom, and he imagines himself chatting easily with the famous talk-show host Jerry Langford. The problem is that Rupert is not yet good, not yet known, and not yet invited anywhere. Martin Scorsese’s film follows what happens when a man confuses wanting attention with deserving it, and De Niro plays that confusion without winking at the audience.
What makes Rupert so unsettling is his politeness. He is not a shouting villain. He says please and thank you, he dresses neatly, and he speaks as if every conversation is already a friendship. De Niro gives him a bright, eager smile and a voice that rises when he is excited. Then, in the next moment, that smile hardens. Rupert does not hear no. He hears not yet. He does not see a boundary. He sees a door that will open if he knocks long enough. That mixture of courtesy and persistence is what makes the film feel so modern, decades before social media made fame feel both close and unreachable.
Fantasy as a way of life
A large part of the film takes place inside Rupert’s imagination. He pictures himself on stage, in Jerry’s office, in a restaurant where famous people laugh at his jokes. Scorsese films those fantasies in the same bright style as the real scenes, so the audience, like Rupert, sometimes has to check what is true. De Niro is essential to that effect. He plays fantasy Rupert with relaxed confidence, and real Rupert with a slightly too-loud laugh and a slightly too-long pause. The difference is small, and that smallness is the tragedy. Rupert is not living in a completely different world. He is living a few inches away from reality, and he cannot feel the gap.
That gap grows when Rupert decides to kidnap Jerry in order to get a spot on his show. The plot sounds like a thriller, but Scorsese and De Niro treat it as a sad comedy. Rupert does not think he is committing a crime so much as arranging a meeting. He is polite to his captive, he offers explanations, and he genuinely believes that once Jerry hears his act, everything will be forgiven. De Niro plays those scenes without malice. Rupert is dangerous precisely because he does not think he is dangerous. He thinks he is finally being fair to himself.
Comedy, cruelty, and the audience
The King of Comedy is also a film about audiences. Jerry Langford is tired, guarded, and surrounded by people who want something from him. Rupert is one of many, but he is the one who will not go away. De Niro and Jerry Lewis, who plays Langford, create a painful contrast: one man who has fame and wants privacy, and one man who has privacy and wants fame. Neither man is happy, and neither man can explain himself to the other. Their conversations are full of missed connections, because Rupert hears encouragement where Jerry offers only professional courtesy.
The film asks a question that has only become more urgent: what do we owe to people who want our attention? And what happens when a culture tells everyone that they can be famous, without telling them how rare fame really is? De Niro’s Rupert is not a simple warning. He is also, at times, sympathetic. He has worked on his act, he has dreams, and he has been ignored by a system that rewards confidence as much as talent. The film does not excuse his actions, but it does show the loneliness underneath them. Rupert wants to be seen, and in a city full of people, being unseen can feel like a kind of erasure.
A performance built on small details
De Niro’s work here is a masterclass in detail. Watch how Rupert holds a tape of his act like a precious object, how he practises his introduction in a mirror, how he laughs a beat too late at someone else’s joke. Watch how his posture changes when he imagines himself as a star: his shoulders drop, his voice deepens, and he suddenly seems at ease. Then watch him return to real life, where his shoulders rise again and his jokes land awkwardly. Those shifts are not big or showy. They are the kind of observations that make a character feel real, even when his behaviour is extreme.
That realism is why Rupert has lasted. Later films and television shows about fame, obsession, and celebrity culture all owe something to this performance. Rupert is not a monster from a horror film. He is a neighbour, a co-worker, a fan who stayed too long. De Niro understood that the most frightening version of such a man is not the one who screams, but the one who smiles and says, I know you will understand, while he does something you cannot understand at all.
Why Rupert Pupkin is a signature role
Among De Niro’s 1970s and 1980s roles, Rupert stands out because he is comic without being safe. The film is funny, but the laughter often catches in the throat. We laugh at Rupert’s delusions, and then we realise that we have also, at some point, rehearsed a conversation that never happened, or imagined a success that never arrived. De Niro does not protect the audience from that recognition. He lets Rupert be both ridiculous and human, both a joke and a warning.
The ending, in which Rupert finally gets his television moment and becomes briefly famous, does not resolve the story neatly. It asks whether fame was ever the point, or whether Rupert simply wanted proof that he existed. De Niro plays that final fame with a strange mixture of triumph and emptiness. Rupert has the audience he wanted, but he does not seem happier for it. He seems, if anything, more alone, because now he must keep performing a self that was built on fantasy.
For Past Tunes readers, that ending resonates with the site’s interest in how culture shapes memory. Songs, films, and television shows do not just entertain us. They teach us what success looks like, and they can make ordinary lives feel inadequate by comparison. Rupert Pupkin is a character who believed that lesson completely. De Niro’s performance remains a powerful reminder to listen more carefully to the people around us, and to ask, before we laugh at someone’s dream, what it costs to keep dreaming when no one is listening.
