The filmmakers of the British drama, Joy, were tasked to find a cast of talented actors to help in recreating the events of one of the biggest medical breakthroughs in history. Directed by Ben Taylor, Joy follows a surgeon, Patrick Steptoe, and a scientist, Robert Edwards, who team together with embryologist nurse Jean Purdy to work on solving the medical puzzle of infertility. The trio pioneers the breakthrough of in vitro fertilization, which ultimately leads to the birth of the world’s first IVF baby, born in 1978.
