Question: How long had Sidney Franklin been directing in 1955? Passage 1:During the Second World War, Hallowes initially served with the 2nd Battalion, the Gordon Highlanders in the defence of Malaya against Japan in 1942. His unit was one of the last to escape into Singapore before the causeway to Malaya was destroyed. When Singapore surrendered on 15 February 1942, Hallowes joined Major "Nick" Nicholson to form one of two pairs of officers who were sent to carry the order to ceasefire to garrisons on the islands of Pulau Blakang Mati and Pulau Brani. They were given permission to try to escape from the Japanese after the order was delivered. They took a boat to the east coast of Sumatra, and walked to Padang, from whence they were rescued by Royal Navy destroyer which called in to refuel after the Battle of the Java Sea. They were shipped to Ceylon, and then flown to India.
Passage 2:Federico Mayor Zaragoza obtained a Ph.D. in pharmacy from the Complutense University of Madrid in 1958.

The following year he was appointed professor in biochemistry at the Autonomous University of Madrid. In 1974 he co-founded the Severo Ochoa Molecular Biology Centre at the Autonomous University of Madrid and the Spanish High Council for Scientific Research. The main focus of Professor Mayor's scientific research has been on molecular brain disease, and he was responsible for drawing up the Spanish National Plan for Mental Health Prevention. He is a member of the Club of Rome, the Club of Budapest, a founder member of the Issyk-Kul Forum. In 2005 he received the Prize Creu de Sant Jordi from the Generalitat de Catalunya.

Passage 3:Metro-Goldwyn-Mayer (MGM) originally announced a remake of the 1925 silent film Ben-Hur in December 1952, ostensibly as a way to spend its Italian assets. Stewart Granger and Robert Taylor were reported to be in the running for the lead. Nine months later, MGM announced it would make the film in CinemaScope, with shooting beginning in 1954. In November 1953, MGM announced it had assigned producer Sam Zimbalist to the picture and hired screenwriter Karl Tunberg to write it. Zimbalist was chosen because he had produced MGM's Best Picture-nominated Christians-and-lions epic Quo Vadis in 1951. The studio then announced in July 1954 that production would start in March 1955 with 42 speaking parts and 97 sets. MGM said Sidney Franklin would direct, that the script by Tunberg was finished, that shooting would occur in Rome and in Spain, and that Marlon Brando was up for the lead. In September 1955, Zimbalist, who continued to claim that Tunberg's script was complete, announced that a $7 million, six-to-seven month production would begin in April 1956 in either Israel or Egypt in MGM's new 65mm widescreen process. MGM, however, suspended production in early 1956.
