AceShowbiz - Rami Malek has signed on to play a real-life Federal Bureau of Investigations (FBI) agent in a new movie.

The project will be based on the book "American Radical", which was written by a Muslim FBI agent under the pseudonym Tamer Elnoury and Kevin Maurer, according to Variety.

The "Mr. Robot" star will portray Elnoury in the film, which will centre on how the agent infiltrated an al-Qaeda terrorist cell. Sam Esmail, who works on Mr. Robot with Malek, is directing and producing. The actor will also serve as a producer.

It is unclear when the film will go into production, but this isn't the first real-life role for Malek - he will be seen on screen portraying late Queen frontman Freddie Mercury in "Bohemian Rhapsody" in November.
