Who co-wrote the screenplay for Terminator 2: Judgment Day with James Cameron?

William Wisher Jr. co-wrote the screenplay for Terminator 2: Judgment Day with James Cameron.

Wisher had already worked with Cameron on The Terminator, contributing to the screenplay and appearing briefly as a police officer in that film. Their collaboration continued when the sequel expanded the original story from a focused chase into a larger science-fiction action narrative.

Terminator 2 was released in 1991 and follows Sarah Connor, her son John, and a reprogrammed T-800 as they try to prevent a future nuclear catastrophe. The screenplay introduced major developments, including the liquid-metal T-1000 and John Connor's role as a future resistance leader.

A common mix-up is confusing the screenplay's writers with the film's producer or director. Cameron directed the movie and co-wrote it, while Wisher was his credited co-writer. Wisher later received additional Terminator-related writing credits, including work connected with Terminator 3: Rise of the Machines.
