Life and career
Bang attended Burnaby North Secondary School, in British Columbia, Canada. Bang's sister, Andrea, is also an actress and writer.

Bang started her career in the Vancouver sketch comedy group Assaulted Fish before becoming an actress. In 2014, Bang played Sook-yin Park, a North Korean chief propagandist in The Interview.

Bang starred as Dr. Allison Mann in the FX on Hulu series Y: The Last Man, which premiered in 2021.
