It's surely no coincidence that Stacy Keach's character is named after Robert Vesco, a notoriously crooked financier who was part of Richard Nixon's criminal network. Vesco supposedly died in 2007, but no body was ever found, so it's possible that this character may be intended to be the real Vesco, who would be 86 in 2021 (Keach is 80).
