In September 2018, Shulman filed suit in Los Angeles Superior Court against the other producers of Charlie Says. The suit says they illegally cut his percentage on the film and only gave him credit for a reduced role. Shulman was recovering from cancer at the time.[9][10][11][12][13] On February 9, 2023, in one of the first jury trials to decide the value of a motion picture producer credit, Shulman was awarded $1.9M, including over $1M in damages related to fraud.[14]
