Harry Potter Producer to Develop OSCAR PILL for Warner Bros.

Warner Bros. has just acquired the film rights to a French youth-fantasy book series called Oscar Pill. Harry Potter producer David Heyman was brought in to produce the film project, which the studio hopes will spark a successful franchise. 

The movie will be called The Adventures of Oscar Pill, is based on French author Eli Anderson's books that tells the story of an unusual teenage boy who can travel inside living beings, including humans.

There are five novels in the series, and here's a little more detailed rundown of the story from the French Wikipedia page, this is a rough translation,

Oscar Pill is a very ordinary teenager until the day he discovers that he has the power to enter human bodies and he belongs to the order of “Médicus”.  His mission is then to fight their enemies, the Pathologus. He will travel across five fabulous worlds of the human body to find each trophy to move to the next world. He will also try to find the mysterious consequences of the death of his father, a great Medicus.

In the first book in the series, Oscar learns that he is a Médicus, then he should go to Cumides Circle to continue his training. The start takes place in a remote prison in Siberia, the great master of Pathologus escaped through a ruse.

This sounds like it could be a really fun movie. I'm sure the studio thinks they may have found a new franchise to replace Harry Potter once it's done, but those are some really hard shoes to fill.
