Ang Daigdig Ko'y Ikaw (lit. 'You Are My World') is 1965 Philippine rom-com co-written, and directed by Efren Reyes starring Fernando Poe Jr. and Susan Roces. The film is FPJ Productions' 3rd anniversary offering and features the then freelancer Roces in her first assignment since leaving Sampaguita Pictures. The film was the first of 17 pictures Poe and Roces would make together and was the beginning of their real life relationship, which would culminate in their marriage three years later. In celebration of the said marriage, the film was re-released to theatres in 1968 which contained footage of the couple's actual marriage ceremony.
