Homo Erectus (released on DVD in the United States as National Lampoon's The Stoned Age) is a 2007 American comedy film written and directed by Adam Rifkin, and starring Giuseppe Andrews, Gary Busey, David Carradine, Ron Jeremy, Ali Larter, Hayes MacArthur, Adam Rifkin, Talia Shire and Sasha Grey in her film acting debut.

Much to his dismay, immediately after he finally expresses his love to her she is "clubbed" by Thudnik (and all that follows in the tradition of caveman stereotypes), and eventually married to him.

Unable to convince the rest of the tribe to stay and fight, Ishbo decides to set out to avenge his father and rescue Fardart on his own.

On the way he gets lost, sees a vision of his father, and stumbles upon a tribe of Amazon cavewomen, who first plan to kill him but are then impressed by his stance against clubbing of women.

The three groups together eventually chase him off the edge of a cliff, where he delivers a thoughtful monologue to the audience before reaching the ground, and his death.

The guide reaches their caveman exhibit, featuring a life-sized "model" of Ishbo, where she explains how with fossils, they have been able to reconstruct the prehistoric cave man and discover how he looked in his life: in her words, "short and fat".
