Quebec singer Robert Charlebois, veteran actor Colm Feore and Dan For Mayor star Fred Ewanuick are part of a sprawling ensemble cast shooting a bilingual comedy about Canada's French-English divide this summer.

Bon Cop Bad Cop producer Kevin Tierney makes his directorial debut with French Immersion, about a group of five English-speakers — one each from Alberta, Saskatchewan, Newfoundland, Ontario and New York — who converge on a small Quebec town to learn French.

The Trotsky director Jacob Tierney joins a cast also including Love and Savagery's Martha Burns, This Hour Has 22 Minutes comic Gavin Crawford, Two and a Half Men's Emmanuelle Vaugier, and Polytechnique lead Karine Vanasse.

Charlebois plays a senator who uses his influence to help the French-language school run by his daughter while Vanasse plays a teacher with a heart of gold.

Publicists say shooting takes place over the next six weeks in Saint-Cesaire, Que., about 60 kilometres east of Montreal.

The film is set for release on Canada Day, July 1, 2011.
