I just saw the movie recently... great movie!
After doing some research, I found a few interesting things...
The movie is based on a book of the same name in 1992.
In 2005, a second book was written by the same author called "Reflex". This story follows two characters from Jumper. One character is abducted and brainwashed to do evil deeds, while the other learns to 'jump' and attempts to track down the first person.
After the movie was made, a third book was written by the same author... "Jumper: Griffin's Story". This book is a spin-off prequel to the movie. It follows the past of another character in the movie whose parents, friends, and family were killed by mysterious assassins. He eventually goes from being the hunted to being the hunter after these mysterious assassins.
Just before the movie was released, a graphic novel was released... "Jumper: Jumpscars". This book was made by two people... not the original author of the other books. This story follows the life of two characters from the movie from when they were Paladins in the past.
Rumor has it that Reflex might be made into a movie with the same actors and actresses. As for the other two, it could happen.
Remember The Mummy Returns? That movie had a character called "The Scorpion King". Well, they made a spin-off prequel called The Scorpion King. Well, "Jumper: Griffin's Story" is a spin-off prequel based on a character in the main movie. So, it could happen.
When Transformers came out in theaters, a graphic novel was also released... a prequel to the movie. No movie has been made on that, but who knows.
