Gregory "Greg" Fowler is the husband of Sheree Fowler and a citizen of Sandford. Throughout the film, it is pointed out that Greg was an extra in Straw Dogs, while his wife also played a cadaver in a crime show.
Later, when the Neighbourhood Watch Alliance is revealed to be a murderous cult and Nicholas Angel is "killed" by Danny Butterman, Nicholas returns to Sandford and a shootout erupts in the town square. When Nicholas first arrives, Greg and Sheree are talking to Reverend Philip Shooter, but when the shooting begins, both Greg and Sheree take cover behind a building's pillars. Greg is shot, in the shoulder, by Danny and falls down. Nicholas then runs halfway towards them and shoots Sheree in the shoulder. Both are arrested later.
- The film credits Greg as "Greg Prosser", but in the Police Station, his surname is Fowler.
- Greg, Sheree and Mr Treacher are the only NWA members who have no lines apart from when they scream in pain after they are taken out
