The Wizards of Waverly Place star will take a lead role in the romantic drama, reports Variety.
The film centres around a high school senior who transfers to a new school and falls for Kali.
It explores the pair's feelings for each other which, while shared, never seem to bear fruit.
Cohen wrote the original script with Nicola Sammeroff, who will also produce with Jason Priestley.
Sulkin currently features in teen television shows Wizards of Waverly Place and Pretty Little Liars and can be seen in films Affluenza and Panda Eyes.
Production on 1990 is scheduled to begin in summer 2013.
