The script is a romanticised version of the true story of how Vincenzo Peruggia, who used to work at the Louvre, walked out one morning with the painting. He kept it at first in Paris and then returned to Italy and told a gallery owner that he had brought the painting back to its birthplace.
Peruggia was arrested but the painting was exibited all over Italy before being returned to the Louvre in 1913.
Hudelson, an art history professor at Palomar College near San Diego, has been obsessed with the theft story of Leonardo da Vinci's most famous creation for a long time.
In his script, the art thief has been portrayed as someone who is in love with Mona Lisa.
"This guy was a simpleton who fell in love with Mona Lisa and in this romanticised version, he claims that in his heart he felt she was lonely and homesick for Italy and that it was his patriotic duty since Napoleon had stolen her from the Uffizi Gallery to take her to the Louvre. He would wrap her in a red shawl and in the early evening holds her up to the window to see Florence," Thompson said.
