In his posthumously published memoirs, Işık described his father as follows: "The most significant thing I remember about him is the way he smelled.
He once noted that his teachers in high school included such significant writers of Turkish literature as Mahir İz, Salah Birsel and Rıfat Ilgaz.
After high school, Ayhan Işık and his cinema partner Sadri Alışık attended the painting department of the State Fine Arts Academy.
In 1952, Akad directed a very significant film called "Kanun Namına" (In the Name of the Law), in which Işık played the leading role mutually with Gülistan Güzey, the femme fatale of Turkish cinema in the 1950s.
However, Ayhan Işık was not satisfied with his lot and visited many countries including Italy and Iran in order to find new possibilities and contacts to market Turkish films.
The film Bitter Life, directed by Metin Erksan, was a second triumph for Işık.
Though Işık worked with most of the best leading actresses of his time, his films with Belgin Doruk occupy a special place.
Işık died in 1979 at the age of 50 from cerebral hemorrhage that comes from sunstroke during a sunbath on the terrace of his house, which shocked his family, friends and fans.
