It was based mostly on known facts caught on video at the time. Bundy's Florida trial was televised. There will be police records of the interrogations if you really want to go the extra mile to ferret out the truth. The judge did throw out one cop's testimony that Bundy confessed to him because the confession itself magically disappeared from the recording of the interview. While we obviously can't know whether everything in the film is factual, I get the strong impression that they made every effort to make it so. You'll have to judge that for yourself.
