Magnum Force is a 1973 American action thriller and the second to feature Clint Eastwood as maverick cop Harry Callahan after the 1971 film Dirty Harry. Ted Post, who also directed Eastwood in the television series Rawhide and the feature film Hang 'Em High, directed this second installment in the Dirty Harry film series, though Eastwood has stated in interviews that the majority of the film was "ghost directed" by himself and second unit director Buddy Van Horn, both of whom would go on to direct later entries in the series. The screenplay was written by John Milius (who provided an uncredited rewrite for the original film) and Michael Cimino. This film features early appearances by David Soul, Tim Matheson and Robert Urich. At 124 minutes, it is also the longest Dirty Harry film.
