The James Bond film series is a series of motion pictures, based on the fictional character of MI6 agent James Bond (code designation "007") appearing in the novels of Ian Fleming. Earlier films were based on Fleming's novels and short stories, followed later by films with original storylines. The franchise remains as one of the longest continually running film series in history, having been in ongoing production from 1962 to 2010 with a six-year hiatus between 1989 and 1995. In that time EON Productions has produced 22 films, at an average of about one every two years, usually produced at Pinewood Studios. The films have grossed just over US$ 5 billion at the worldwide box office, being the second most-successful film series ever. In addition, there are two independent productions and an American television adaptation of the first novel. Albert Broccoli and Harry Saltzman co-produced the EON films until 1975, when Broccoli became the sole producer. Since 1995, Broccoli's daughter Barbara and stepson Michael G. Wilson have co-produced them. Six actors have portrayed 007 in the official EON series so far (not counting stunt doubles, authorised video game voiceovers, etc.).
