Under the direction of young Claude Lelouch who later became one of most acclaimed French directors, Dalida was dressed as a soldier, walked through a war-torn forest in the middle of the bombs and had accompanied real scenes from the Second World War. An unusual image of Dalida found its public and was a hit in cafes. Alongside Dalida's performance of the song on 26 September, in front of a crowd of 2,000 people on the first floor of the Eiffel Tower, "Le jour le plus long" topped charts in France for two weeks and earned her another gold disc. Dalida fully spent 1963 delivering live appearance across the whole world and dedicating herself more to Canadian youth public, as in France the yé-yé experienced its greatest swing in this period. Her world tour was a success, with sold out concerts in Europe from Portugal to Poland, Canada, Asia, Fort-de-France, Latin America and the Arabian countries. In Algeria, she became the first artist to appear since the proclamation of independence. Dalida also dedicated the late summer period again to filming, so she went to Hong Kong for three months to star in B movie L'Inconnue de Hong-Kong, alongside Serge Gainsbourg. Although the movie was a commercial flop, Dalida received favorable reviews. In January 1963 at Cortina d'Ampezzo, Dalida was awarded with the Oscar Mondiale del Successo dei Juke Box award for the most listened artist on the jukeboxes in Europe. Later the same month, she made a shift from yé-yé covering Ben E. King's "Stand by Me" as "Tu croiras", which was followed by an equally more melancholic string of recordings such as "Le jour du retour", a summer number one hit in Canada, and "Eux" that later peaked at number two in Argentina and was recorded in five languages. "Eux" was awarded with the Oscar mundial du success du disque for drawing the most international sales by a French artist in 1963, and Dalida named her fourteenth studio album after it. The 1963 world tour was prolonged into 1964 only with several short breaks. The tour's French leg started on 11 April 1964, after which Dalida traveled 30,000 kilometers solely by car during its five-month run, with a public attendance over 200,000. "The most iconic moment of tour" as said by her brother Orlando, was a concert at Draguignan on 14 August when "Dalida appeared with blond hair for the first time, and shocked the crowd that that didn't recognized her at first glance".
