Rise of the Planet of the Apes director Rupert Wyatt is already planning a sequel.

The movie - starring James Franco as San Francisco scientist Will Rodman and Frieda Pinto as primatologist Caroline Aranha - performed strongly on its US release last weekend, and Rupert believes the possibilities for a new film are endless.

"There's so much we could do. The ideas I've had are all sorts of things, ranging from Full Metal Jacket with apes, you could start this story again eight years from where we left off, the next generation of apes, those that have come from our protagonists, perhaps going in to a conflict with humans and showing real fear, in the same way as going into war for young soldiers in this day and age, telling their story."

Rupert believes the interactions between apes and humans is a fascinating story and is keen to explore this more in any future sequels: "Or we could look at how apes are taking over cities, and being moved into human environments and having to interact with them and deal with things that are part of our culture and understand and evolve through them. Spies that are in the employ of the apes, working against humans and humans maybe existing underground, because that's a way they can avoid the virus, coming up above ground wearing gas masks, and maybe that's what dehumanizes them."
