Liam Hemsworth & The Rock Mull Empire State

Liam Hemsworth is all but locked while Dwayne Johnson is in talks to star in the indie heist thriller Empire State says Deadline.

The film--previously titled "The Sentry Keep"-- is based on the true story of a 1982 NYC armored car company robbery thought at the time to be the largest cash heist in U.S. history.

Adam Mazer wrote the script from which Dito Montiel ("Fighting," "The Son Of No One") is calling action.

David Hoberman and Todd Lieberman are producing the film

Production will begin in April.
