Thomas Dekker is set to play John Connor in Fox’s drama pilot “The Sarah Connor Chronicles,” from WBTV and C2, the company of “Terminator 3: Rise of the Machines” producers Mario Kassar and Andrew Vajna.

Written by Josh Friedman, the project takes place after the events depicted in “Terminator 2: Judgment Day” and follows Sarah Connor (Lena Headey), a modern warrior and loving single mom to 15-year-old son John (Dekker).
