Thanks to Ender Wiggin for noticing that on the Ender’s Game full cast and crew webpage on IMDB Steve Jablonsky is now listed as the composer for the Ender’s Game film score. Remember that anyone with a pro account on IMDB can go in and change things in the profiles. So this is pure rumor and observation.
In the past we had a previous rumor that James Horner had signed on to become composer for Ender’s Game but it was never confirmed by Summit. Though James Horner would have been really awesome to have, if Steve Jablonsky is truly the new composer we look forward to hearing what he creates for Ender’s Game.
