The paper said Caan and Duvall -- who were involved in developing the game -- will reprise their roles as Sonny Corleone and Tom Hagen from Francis Ford Coppola's trilogy of "Godfather" films.
The late Marlon Brando agreed before his death last July to do voiceover work and provide likenesses for the game. The Reporter said Brando virtually reprised his Oscar-winning role as Don Vito Corleone for the video game.
Electronic Arts has also secured the rights to composer Nino Rota's "Godfather" musical score.
The paper said Caan and Duvall are scheduled to attend an unveiling of the game in New York's Little Italy on Feb. 10.
