Spacey and director George Hickenlooper met with Abramoff on Friday to prepare for a film based loosely on Abramoff's career in Washington. It will be called "Bagman" or "Casino Jack."
Spacey, the star of "American Beauty" and "The Usual Suspects," will play Abramoff.
Abramoff is serving time for mail fraud, tax evasion and other offenses stemming partly from a federal probe of influence-peddling in Washington.
Shooting will begin in May, with a release targeted for the summer of 2011, according to Hannibal Pictures Chairman Richard Rionda Del Castro.
