TOKYO — David Fincher’s “The Social Network” will open the Tokyo Intl. Film Festival, the fest announced on Tuesday.

Ben Affleck’s suspenser-actioner “The Town” is skedded to close the 23rd edition of the fest, which will unspool Oct. 23-31 in Tokyo.

The lineup of guests has yet to be announced, but given the fest’s track record as a B.O. launch pad for its opening and closing pics, talent from “The Social Network” and “The Town” will no doubt be present in force.

The opening pic last year, “Avatar,” finished its Japan run with nearly $180 million.

“The Social Network” is skedded for release by Sony on Jan. 15, while Warner will bow “The Town” sometime in 2011.

The Tokyo fest also announced a special screening of Claude Chabrol’s 2009 pic “Bellamy,” as a tribute to the late helmer, who died on Sept. 12, as well as the 10-pic lineup of its World Cinema section, which will include Roman Polanski’s “The Ghost Writer” and Michel Gondry’s “Thorn in the Heart.” Pics in this section have screened at major fests around the world, but have not yet secured a Japan distribution deal.
