The ranks of Warner Bros.' adaptation of J.K. Rowling's "Fantastic Beasts and Where to Find Them" continues to grow as actress Jenn Murray joins the cast in an unspecified "key role."

The Wrap reported the casting news and revealed that Murray will share scenes with the rival of Eddie Redmayne's Newt Scamander, the role Ezra Miller is reportedly up for in the film -- although the actor has yet to officially join the cast.

Taking place about seventy years before the events of the Harry Potter saga, "Fantastic Beasts" follows Scamander, the author of the eponymous Hogwarts textbook, as he arrives in New York during his quest to study and document the magical creatures of the world. Alongside Redmayne, possibly Miller and now Murray, Katherine Waterston and Alison Sudol co-star as sisters Tina and Queenie; Dan Fogler as muggle Jacob; Faith Wood-Blagrove as Modesty; and recently announced Colin Farrell as Graves.

Direct by David Yates and penned by "Harry Potter" scribe J.K. Rowling, "Fantastic Beasts and Where to Find Them" arrives in theaters November 18, 2016.
