In an interview with the Associated Press, Spacey says Abramoff was a movie buff who was always doing impressions. Spacey is a talented impressionist, too, so he made sure several impersonations were added to the script.
Director George Hickenlooper, who died October 30th of an accidental overdose of ethanol and oxymorphone at the age of 47, said when Spacey met with Abramoff in prison, the visit ended with them trading impressions.
Spacey is up for a Golden Globe for his performance.
Abramoff served 3 1/2 years in federal custody for fraud, corruption and conspiracy. He is now on probation.
