Oscar-nominated actress Shohreh Aghdashloo, John Corbett and Ebon Moss-Bachrach have joined the cast of "Il Mare" (working title) for Warner Bros. Pictures and Village Roadshow.

They join Keanu Reeves, Sandra Bullock and Christopher Plummer in the picture, which is based on the 2000 Korean romance/sci-fi feature, "Siworae." The story revolves around two people (Reeves and Bullock) who fall in love via a mysterious mailbox.

Aghdashloo is set to play Bullock's medical colleague and confidante. Corbett will star as Bullock's former fiance. Moss-Bachrach will play Reeves' younger brother. Also joining the cast is veteran Dutch actress Willeke van Ammelrooy ("Antonia's Line"), who will play Bullock's widowed mother.

"Il Mare," which is shooting in Chicago, is being directed by Alejandro Agresti and produced by Doug Davison and Roy Lee of Vertigo Entertainment. Vertigo's Sonny Mallhi is the co-producer. The executive producers are Mary McLaglen, Erwin Stoff, Robert Kirby and Bruce Berman. The screenplay is by the Pulitzer Prize-winning playwright David Auburn ("Proof").

The key filmmaking crew includes cinematographer David Tattersall, production designer Nathan Crowley, composer Paul M. van Brugge and Agresti's longtime film editor, Alejandro Brodersohn.

"Il Mare" will be released worldwide next year by Warners, with Village Roadshow handling select territories.

Aghdashloo and Corbett are repped by CAA. Moss-Bachrach is repped by the Gersh Agency and Benderspink.
