The James Bond film series is a British series of spy films based on the fictional character of MI6 agent James Bond, '007', who originally appeared in a series of books by Ian Fleming. It is one of the longest continually running film series in history, having been in ongoing production from 1962 to the present (with a six-year hiatus between 1989 and 1995). In that time, Eon Productions has produced 25 films as of 2021, most of them at Pinewood Studios. With a combined gross of over $7 billion to date, the films produced by Eon constitute the sixth-highest-grossing film series. Six actors have portrayed 007 in the Eon series, the latest being Daniel Craig. Albert R. Broccoli and Harry Saltzman co-produced most of the Eon films until 1975, when Broccoli became the sole producer. The single exception during this period was Thunderball, on which Broccoli and Saltzman became executive producers while Kevin McClory produced. From 1984 Broccoli was joined by his stepson Michael G. Wilson as producer and in 1995 Broccoli stepped aside from Eon and was replaced by his daughter Barbara, who has co-produced with Wilson since. Broccoli's (and until 1975, Saltzman's) family company, Danjaq, has held ownership of the series through Eon, and maintained co-ownership with United Artists since the mid-1970s. The Eon series has seen continuity both in the main actors and in the production crews, with directors, writers, composers, production designers, and others employed through a number of films.
