Michael Mann and Johnny Depp will make Public Enemies for Universal, according to Variety. Mann wrote the script, based on Bryan Burrough's 2004 novel.
The drama is set during the great crime wave of 1933-34, when the government's attempts to stop Depression-era criminal legends such as John Dillilnger, Baby Face Nelson and Pretty Boy Floyd transformed J. Edgar Hoover's FBI into the country's first federal police force.
Depp will play John Dillinger, considered the most notorious gangster of the era. The film will begin shooting in Chicago on March 10.
