The four principals at Rhombus Media have gone their separate ways — sort of — following a breakup of the team behind The Red Violin and Yo-Yo Ma: Inspired by Bach. Sheena Macdonald announced on Wednesday she is exiting the Toronto shop to take a job at the Canadian Film Centre, while the remaining bosses will continue to work together, under both the Rhombus name and through their own production companies.

Niv Fichman, Barbara Willis Sweete and Larry Weinstein — who founded the company 28 years ago — insist they are parting on good terms, though the break-up follows months of rumor and one notable public remark that the company was in trouble.

Six months ago, Weinstein told a Toronto newspaper that the company was coming undone because of creative differences among its top execs, only to backpedal a few days later, telling Playback ‘We’re all good.’ He added at the time that if Rhombus were to break up, it would be mutual and announced jointly, a prediction that more or less came true on Thursday.

The company’s work has recently been split between big-budget, international movie projects such as the upcoming Silk, thought to be favored by Fichman, and the performing arts specials on which the company was built such as Elizabeth Rex and Beethoven’s Hair.

Fichman, Willis Sweete and Weinstein will reportedly continue to co-own the Rhombus library. Macdonald, meanwhile, starts May 14 as director of special projects at CFC, where she will work to expand the center’s presence in the international marketplace.
