In October 2018, Selma Blair announced to her fans that she had been diagnosed with multiple sclerosis, an incurable debilitating neurological condition in which the immune system eats away at the protective covering of nerves. New documentary Introducing, Selma Blair details the American actress’ journey with the condition and follows her as she undertakes stem cell treatment. The film shows Blair at her rawest, depleted by chemotherapy and consumed by her condition. Director Rachel Fleit said the crew worked around Blair’s symptoms.
