Planet of the Apes
Charlton Heston and Roddy McDowall star in this legendary science fiction masterpiece. Astronaut Taylor (Heston) crash lands on a distant planet ruled by apes who use a primitive race of humans for experimentation and sport. Soon Taylor finds himself among the hunted, his life in the hands of a benevolent chimpanzee scientist (McDowall).

Beneath the Planet of the Apes
In the acclaimed sequel to Planet of the Apes, another astronaut (James Franciscus) crashes through the time barrier searching for the missing Taylor. The daring rescue leads to a subterranean city where mutant humans, who practice mind control, worship a weapon capable of destroying the entire planet. Both an action-oriented science-fiction adventure and a wry commentary on today's world, it's imaginative entertainment for fantasy buffs of all ages.

Escape From the Planet of the Apes
Roddy McDowall and Kim Hunter reprise their roles from the original Planet of the Apes in this third chapter of the Apes saga. Two intelligent simians from the future, Cornelius (McDowall) and Zire (Hunter) travel to present-day Earth. They become instant sensations, wined and dined and treated like celebrities—until a high-level plot forces them to run for their lives.

Conquest of the Planet of the Apes
Colourful, futuristic sets, a relentless pace and an action-packed climax highlight the fourth episode of the legendary Apes saga, starring Roddy McDowall and Ricardo Montalban. The time is the near future. Apes have supplanted dogs and cats as household pets, and replaced servants as personal assistants—until their continual mistreatment provokes one advanced ape from the future, Caesar (McDowall), to lead a spectacular revolt. It's thrilling science fiction that offers both a serious message and stirring entertainment.

Battle for the Planet of the Apes
Roddy McDowall and Claude Akins star in the fifth and last chapter of the legendary Apes saga. Set in 2670 A.D., an idyllic society of man and ape is threatened by both a militant gorilla (Akins) and a tribe of still-intelligent mutant humans. Finally, simmering tensions dividing the primates erupt in an apocalyptic climax. When the smoke clears, the carnage is everywhere, but there is hope for a new beginning for man and ape. Co-starring John Huston, Paul Williams, and Lew Ayres.
