Orange Is the New Black

Laverne Cox's twin brother, musician M. Lamar, appears in a flashback as Sophia before her gender transition.

Uzo Aduba's character was only meant to appear in the first three episodes. After seeing her performances, the writers and producers made her a recurring character.

Based on the 2010 memoir 'Orange Is the New Black: My Year in a Women's Prison', Piper Kerman's book about the 13 months of a 15-month sentence that she served at a federal correctional facility in Danbury, Connecticut. The show changes Kerman's last name to Chapman.
