The Rocky Horror Picture Show has almost no family in it, which is exactly why it is worth diagramming. Richard O'Brien's 1973 stage musical reached the screen in 1975 with Tim Curry carrying Dr. Frank-N-Furter over from the Royal Court, and the household he presides over is held together by service, appetite, invention and murder rather than by descent. A genogram is built to show both kinds of tie at once — the blood lines in one notation, the attachments in another — so a film where the second sort does all the work makes an unusually legible chart.
Only two pieces of ordinary kinship are asserted anywhere in the film. Riff Raff, the handyman, and Magenta, the domestic, are brother and sister; and Dr. Everett V. Scott arrives at the castle looking for his nephew Eddie, who had written to him. Neither pair's parents are named or shown, so the diagram draws them as unknown — a genogram cannot express siblinghood as a link between two siblings, only as a shared parental union, which is why four unnamed figures sit along the top of this chart carrying no information except that the people below them are related. The Riff Raff and Magenta pairing is then complicated by the staging, which presents them as considerably closer than siblings without ever saying so; the chart marks that as an enmeshed tie rather than as a union, because the film declines to commit and so should the diagram.
Everything else is attachment. Columbia was Frank-N-Furter's lover before Eddie and Eddie's afterwards, and her accusation at the dinner table — that Frank chewed Eddie up and spat him out — is the only grief the house permits itself. Brad Majors and Janet Weiss arrive engaged that same afternoon and are separately seduced by Frank in the dark, each under the other's likeness, within hours of the flat tyre that stranded them. Janet then goes to Rocky. Dr. Scott turns out to be Brad's old science teacher, and is the single figure standing in both households, which is what makes the two halves of the chart one picture rather than two.
The hardest node to place is Rocky Horror himself. Frank builds him in the laboratory as a mate to specification, and announces at dinner that he was made with half of Eddie's brain — the half taken before Frank killed Eddie with an ice axe and served the remains to his guests. That leaves Rocky with two sources and no parents, so this chart hangs him beneath the Frank–Eddie line: the notation doing an unusual job, not a claim that the film depicts a conventional parentage. It reads correctly, which is the point. Frank is also drawn as Rocky's partner, so the same two figures are joined twice over, and the loop that produces is not a defect in the chart. It is the argument of the film.
Tim Curry died on 25 August 2026, aged 80, at his home in Toluca Lake. He had played a great many other parts — Clue, Muppet Treasure Island, the miniseries of IT — but the one at the centre of this chart is the one that made a midnight ritual out of a low-budget musical and kept it running for fifty years. This page is a relationship chart rather than an obituary, and Frank-N-Furter is at the middle of it because the film puts him there: every other character in the castle has a line running to him, which is why he is drawn on a row of his own.
