Via Deadline:

Asa Butterfield is Ender in the Ender's Game movie

Asa Butterfield, the 14-year old title star of Martin Scorsese’s 3D film Hugo, has been offered the title role in Ender’s Game, the Odd Lot Entertainment adaptation of the Orson Scott Card science fiction novel.

The kid looks the part. He’s small and has intelligent eyes. Plus, Scorsese casting him as the lead in Hugo certainly lends credibility to his casting chops and ability to hold his own as the star of a big budget film. It’s all just rumour now, however; but it’s fun to speculate.
