Episode #1.2 - S1-E2
Factual error: The episode is set in 1977 and Edmund tells Ford that Frances Farmer had a lobotomy. However, the first report of Farmer having a lobotomy came from the 1978 novel "Shadowland" by William Arnold. It was subsequently revealed that some of the events were completely made up by Arnold, including the fact she had a lobotomy. There was never any allegation or suggestion that Farmer had a lobotomy while hospitalized in the 40's.
