Anonymous Rex is a 2004 science fiction film directed by Julian Jarrold and starring Sam Trammell and Daniel Baldwin.

In an alternate timeline, dinosaurs have managed to survive the KT Extinction Event, having since evolved into humanoid forms and now live amongst humans using hard light holographic disguises (formerly rubber suits, paper masks, etc).

When the pair investigate the crime scene, Vincent notices the scent of another dinosaur on the windowsill, concluding it was not a suicide.

At the funeral Vincent talks to a man dressed in a strange suit who belongs to the cult that the deceased had previously joined, "The Voice of Progress."

Vincent and Ernie go to the cult meeting where they are told the Voice of Progress' ideals and history: The Voice of Progress is revealed to be both the title of their leader and a collection of dinosaurs who believe that the prolonged use of disguises has robbed the dinosaur community of its unique identity.
