Who owns interview quotes: subject or writer?

The quotations in published interviews are valuable source material for journalists, book authors and film makers. But who owns their copyrights: the subjects who were quoted, or the writer who conducted the interview? That question has attracted recent attention on both sides of the U.S.-Canadian border. To the south, New York City lawyer Mark Fowler (of Satterlee Stephens Burke & Burke) considered the question in a Rights of Writers post titled Who "Owns" an Interview. North of the border, Bob Tarantino provides a Canadian law persective in Question and Answer: Who Owns the Copyright in an Interview? - a post in Heenan Blaikie's Entertainment & Media Law Signal.
