Former Redstone Son-in-Law Quits Theater Chain

Ira A. Korff has resigned as president and director of National Amusements Ltd., the Dedham, Mass.-based movie theater company controlled by his former father-in-law, Viacom Inc. Chairman Sumner Redstone. No successor has been named by the closely held company, which owns 850 movie screens and is the controlling shareholder of Viacom.

Korff, 44, was divorced two years ago from Redstone’s only daughter, Shari E. Redstone, who joined the executive ranks of National Amusements last year. Korff, a rabbi who holds a doctorate in international law, was the theater chain’s chief operating officer for eight years and supervised its expansion in Britain.

Redstone said Korff has a long-term consulting contract with National Amusements, and added: “Ira remains a member of my family and the father of my grandchildren. Neither his business nor personal relationship with me has been affected by the divorce.”

In a telephone interview, Korff said he is associated with the Boston law firm of Lewenberg & Korff and is exploring electronic delivery of the Jewish Advocate, a weekly newspaper he owns.
