Will Ferrell is set to star as former president Ronald Reagan.
The actor, 48, will portray the 40th president of the United States in the upcoming film Reagan, a Black List script written by Mike Rosolio, according to The Hollywood Reporter.
The story takes place during the beginning of President Reagan's second term. In the movie he "falls into dementia," according to the Black List, an annual survey of notable new screenplays, reports THR. "An ambitious intern" is then "tasked with convincing the commander-in-chief that he is an actor playing the President in a movie."
In November 1994, five years after he left office, Reagan announced that he had Alzheimer's. He died almost 10 years later on June 5, 2004.
Twitter quickly reacted to news of the project, criticizing the upcoming film for treating the subject of Alzheimers insensitively.
President Reagan's son, Michael, was one of the first to speak out against the film.
"Alzheimers is not a comedy first it robs you then it kills you," he wrote.

Many others agreed with Reagan's sentiment, also speaking out against the subject of the film.
"Alzheimer 's is by no means funny. It kills treasured memories and robs you of your very existence," wrote one user.

R/T If you think mocking President Reagan's battle with dementia by way of a comedy movie is insensitive to people afflicted by that illness— John Miller (@JVM225) April 28, 2016
This movie mocks Reagan's fight with alzheimers. All involved should be ashamed. https://t.co/5JRtyW5Vfb— Sarah Connor (@SConnorTX) April 28, 2016
Ferrell, who has previously played President George W. Bush in Saturday Night Live skits, will also serve as a producer on the project.
