Build a movie plot around this: Who is Egyptologist Simone Choule's friend that Trelkovsky meets? Stella
The answer to this question is:
Trelkovsky (Roman Polanski), a quiet and unassuming man, rents an apartment in Paris whose previous tenant, Egyptologist Simone Choule, attempted to commit suicide by throwing herself out the window and through a pane of glass below. He visits Choule in the hospital but finds her entirely in bandages and unable to talk. Whilst still at Choule's bedside, Trelkovsky meets Simone's friend, Stella (Isabelle Adjani), who has also come to visit. Stella begins talking to Simone, who becomes aware of her visitors. Initially showing some signs of agitation upon seeing them, Choule soon lets out a disturbing cry, then dies. It isn't clear which of the two has caused this reaction. Apparently unaware that Choule is now dead, Trelkovsky tries to comfort Stella but dares not say that he never knew Simone, instead pretending to be another friend. They leave together and go out for a drink and a movie (1973's Enter The Dragon), where they fondle each other. Outside the theatre they part ways.As Trelkovsky occupies the apartment he is chastised unreasonably by his neighbors and landlord, Monsieur Zy (Melvyn Douglas), for hosting a party with his friends, apparently having a woman over, making too much noise in general, and not joining in on a petition against another neighbor. Trelkovsky attempts to adapt to his situation, but is increasingly disturbed by the apartment and the other tenants. He frequently sees his neighbors standing motionless in the toilet room (which he can see from his own window), and discovers a hole in the wall with a human tooth stashed inside. He receives a visit and a letter from one Georges Badar (Rufus), who secretly loves Simone and has believed her to be alive and well. Trelkovsky updates and comforts the man and spends the night out with him. Gradually he changes his breakfast habits to those of Simone, and shifts from Gauloises to Marlboro cigarettes.Trelkovsky becomes severely agitated and enraged when his apartment is robbed, while his neighbors and the concierge (Shelley Winters) continue...
