Filmmaker Nathalie Bibeau talks with host Colin Ellis about her new doc, The Walrus and the Whistleblower, which features a former animal trainer who spoke up about alleged abuse at Marineland in Niagara Falls, Ont. She describes Phil Demers's uniquely close relationship with Smooshi, a captive walrus who had imprinted on him, his dream of being reunited with her, and his fight against the theme park, which is suing him for $1.5 million. The Walrus and the Whistleblower is streaming on CBC Gem.
