Despite this, one thing that persists is a variety of names and aliases employed by the titular character, and the assassin whose codename is the Jackal. In the series, this Jackal is played by Eddie Redmayne, and despite going by a dozen or so different identities, the Jackal appears to be the codename that sticks, and becomes the key identifier for groups like MI6 and potential customers. However, the story behind this codename is not clearly shown in the series.

His Real Identity Is Even More Complex Than The Codename





While the Jackal serves as a codename, the man behind this moniker is an even bigger mystery. His wife, Nuria, knows him as Charles Calthorp, a wealthy English businessman with whom she has a son. However, he uses over a dozen names, identities, and costumes to conceal his identity. Within the context of the show, it appears that his actual name is Alexander Duggan, which was the name he was referred to by the British army and his peers before he began his freelance career as a mercenary for hire.
While the Jackal serves as a codename, the man behind this moniker is an even bigger mystery.
Alexander Duggan is, by all official accounts, dead. He died in Afghanistan along with the rest of his unit when they drove over a landmine. However, this was actually the doing of Alexander Duggan himself, who grew disillusioned of the army and the less savory things he witnessed as a soldier. Now, it’s likely that he identifies more with his life as Charles Calthorp than he does to his original name, as his new identity is the one he used to form a family. Meanwhile, he also uses many other identities to complete his work in The Day of the Jackal.
