An image from the production The Coca-Cola Case. (Argus Films/NFB) It seems that a documentary critical of soft-drink giant Coca-Cola has left a bitter taste with the company.

The multinational corporation has told a university film network planning to screen The Coca-Cola Case in several cities that the movie contains inaccuracies and violates a confidentiality agreement.

The Montreal-based group, called Cinema Politica, says Coke lawyers sent it a letter earlier this month issuing veiled legal threats if it proceeds with plans to host screenings in Canada, the United States and abroad.

But the group's programmer, Ezra Winton, says they plan to go ahead with a screening in Montreal Monday. Their own legal counsel has said they are within their rights to show the film.

The Coca-Cola Case, co-produced by Argus Films of Montreal and the National Film Board of Canada, links Coca-Cola to human rights abuses and anti-union tactics in Colombia and Guatemala.

In the letter to Cinema Politica provided by the group, Faith Gay of New York law firm Quinn Emanuel says "the Coca-Cola Company reserves all of its rights and remedies with regard to any future showing of the film."

Winton said The Coca-Cola Case would begin its tour as planned Monday night at Montreal's Concordia University and continue through March. Other stops include Halifax, Fredericton, Toronto, Saskatoon, Lethbridge, Alta., Vancouver and Yellowknife.

The handful of international screenings include Woods Hole, Mass.; Stockholm, Sweden; Trondheim, Norway; and Auckland, New Zealand.

'We're planning to go ahead'

A spokeswoman for Coca-Cola said the company took issue with the film on several points.

"The unfounded allegations made in the documentary have been reviewed by multiple courts in Colombia and the United States, as well by the International Labor Organization, and outside law firms — all concluding that the Coca-Cola bottler employees in Colombia enjoy extensive, normal relations with multiple unions and are provided with safe working conditions there," Kerry Kerr said Monday in an email.

Winton said The Coca-Cola Case, directed by Carmen Garcia and German Gutierrez, screened without incident at the Montreal International Documentary Festival last November.

Cinema Politica, a non-profit organization, has 55 member groups across the country and another dozen around the world.
