The Substitute is a 1993 American television film directed by Martin Donovan, written by David S. Goyer under his pseudonym Cynthia Verlaine, and is also Mark Wahlberg's first acting role and credited as "Marky Mark", due to his successful hip hop career.
The Substitute is written by Cynthia Verlaine, who does not really exist.
I wrote that Cynthia Verlaine does not really exist, since she is only a pseudonym of the actual screenwriter.  I think the AI doesn't know that being a pseudonym means being nonexistent.
