terribly inaccurate film (spoilers)
if you're looking for historical accuracy, don't look toward this film. the movie is filled with all sorts of terrible representations. Mostly, Carr is completely misrepresented.
* There is zero evidence that Kammerer and Carr ever had a sexual relationship (read Dennis McNally and Burroughs on this matter).
* Kammerer did not write Carr's papers; Carr was actually an exceptionally capable student.
* Carr confessed to the DA without the assistance of Ginsberg, but with the help of Carr's mother. That entire bit about Ginsberg writing the confession, and turning it into his professor, and that being why he was expelled, and that the professor mailed it back to him....that's all completely fabricated. There was never any such document. Carr confessed on his own (with his mother by his side).
* Carr did not try to kill himself while in jail.
* Carr had a great relationship with his professor (Lionel Trilling).
* "Honor slaying" never appeared in any law or legal book.
* Carr remained lifelong friends with Ginsberg, Kerouac, and Burroughs. Carr edited their work, gave them advice, and used his power as a UPI editor to help promote their causes. For some reason, the ending of the movie implies he had a falling out with the Beats and never wanted anything to do with them again. Not true.
Smaller issues:
* Kammerer tried to hang Kerouac cat, not gas him.
* Kerouac's bail was $100, not $5000.
