Juno Temple plays Bettye McCartt in the Paramount+ series The Offer, but is the character based on a real person? The Offer is about the true exploits of producer Albert S. Ruddy in trying to get The Godfather made. The series stars Miles Teller as Ruddy, while the supporting cast is filled with real-life figures, from producer Robert Evans (Matthew Goode) to director Francis Ford Coppola (Dan Fogler). However, Bettye McCartt is not someone whose important work behind the scenes is all well known.
