The Assassination Bureau was a movie made in 1969 based on the unfinished book by Jack London. It stars Oliver Reed, Diana Rigg, and Telly Savalas.

In the movie, Miss Winter (Rigg), a journalist, discovers an organization devoted to killing for money known as the Assassination Bureau Limited. Thinking to bring an end to the bureau, she cleverly commissions an assassination, that of the chairman of the bureau himself, Ivan Dragomiloff (Reed). Rather than upset, Ivan is amused and intrigued by the proposition and accepts it, leading to a mad chase across Europe. Either his colleagues must kill him or he will kill them.
