Who wrote the screenplay for David Fincher's Se7en?

Andrew Kevin Walker wrote the screenplay for David Fincher's Se7en. Walker completed the script in 1991 after drawing on his experiences and impressions of New York City, creating the bleak crime story about detectives investigating murders themed around the seven deadly sins.

The screenplay was purchased by New Line Cinema, but production was delayed while the project moved through development. Jeremiah S. Chechik was initially attached to direct and requested changes, including removing the film's notorious final revelation. Fincher later agreed to direct after reading a draft that retained the original ending.

During production, the studio considered softening the story because it viewed the material as exceptionally dark. Fincher and star Morgan Freeman supported Walker's original screenplay, helping preserve its grim structure and ending. The finished film was released in 1995 and became a major critical and commercial success.

A frequent credit mix-up comes from Fincher's strong creative identity: he directed Se7en and helped shape its visual style, but he did not write the screenplay. Walker also later worked with Fincher on uncredited rewrites for The Game.
