Canadian-led Los Angeles production company Therapy Content has secured the film development rights to Terry Fox: The Feature Film from the family of Terry Fox and The Terry Fox Foundation.

The deal was announced Friday, 33 years to the day Fox began his famous cross-Canada marathon.

The film will track Fox’s story as the 21-year-old amputee and bone-cancer survivor embarked on his journey that saw him run the equivalent of a full 42-KM marathon every day over 143 days. He started in St. John’s NL and made it as far as Thunder Bay before cancer again caught up with him. He died in June 1981.

Kelly Slattery, a Therapy Content producer and a Toronto native, said in a statement that 100% of the film’s profits will go to cancer research managed by the Vancouver-based Terry Fox Research Institute.

Slattery has a family connection to the story: her father was an Adidas executive who had received a letter from Fox when he was seeking a running-shoe company to support him, as he would wear out shoes in a matter of days during his run.

The film’s release is planned for December 2014.

Therapy Content’s credits include Robert Barry Ptolemy’s Transcendent Man and musician Dave Grohl’s Sound City. Both are documentaries.
