Nash is shown to join Wheeler Laboratory at MIT, but there is no such lab. Instead, he was appointed as C. L. E. Moore instructor at MIT, and later as a professor. The film furthermore does not touch on the revolutionary work of John Nash in differential geometry and partial differential equations, such as the Nash embedding theorem or his proof of Hilbert's nineteenth problem, work which he did in his time at MIT and for which he was given the Abel Prize in 2015. The so-called pen ceremony tradition at Princeton shown in the film is completely fictitious. The film has Nash saying in 1994: "I take the newer medications", but in fact, he did not take any medication from 1970 onwards, something highlighted in Nasar's biography. Howard later stated that they added the line of dialogue because they worried that the film would be criticized for suggesting that all people with schizophrenia can overcome their illness without medication. In addition, Nash never gave an acceptance speech for his Nobel prize.
