Director Aneesh Chaganty wanted an actress who really uses a wheelchair to star as a teenaged girl with disabilities in his new thriller, “Run.” And she needed to be able to do action scenes. He found Columbia University student Kiera Allen. Now on Hulu, “Run” tells the story of a mother-daughter relationship gone extremely awry. It’s the first thriller to star an actor who uses a wheelchair since the 1940s.
