Filming started in October 1969 in Israel, in Tel Aviv and Jaffa. Two weeks into filming director Uri Zohar left the production. After a week Harris took over as director. Since Harris was not a member of a technical union a crew union ordered its members to stop working but they continued anyway. "No other director would take over without months of preparation," claimed Harris.
Harris was meant to be in Israel for five weeks and ended up staying five months, causing him to miss out on playing the title role in the film Scrooge (Albert Finney took the role).
After he made the film Harris said he felt like putting an ad in Variety apologizing to all the directors he had worked with. Cinematographer Otto Heller died two weeks after filming.
Location shooting took place around Tel Aviv, particularly at the Bloomfield Stadium. Interiors were shot at Twickenham Studios in London. The film's sets were designed by the art director Richard Macdonald.
