Thanks Brosa!!!! 
According to TheNewsPK, they might film Eldest. I think the OP got his details from Inheriwiki (Can never trust Wiki).
20th Century Fox currently holds the rights from Knopf to produce the sequel Eldest, and there have been rumors of it being released in Summer of 2011; however, this information is currently uncertain as they are making no statement to support the claim.

Edward Speleers has stated that he was training up for a second movie, and an unofficial report said something about the movie being filmed which is a good sign for many that Eldest The Movie, will be made. However, Garrett Hedlund is playing Louis in the movie Hectic (2008), so it is possible that they are waiting for “Murtagh” to come back. More information will be posted on this page as it comes in. According to IMDB website, John Malkovich has several movies in the making, all these movies with 2008 dates.
It was also said in a press release by 20th Century Fox that there will be a feature on the upcoming Eragon DVD called “Just The Beginning” that will give us a “postmortem look at what’s to come in the film series”
Eragon didn’t do well in the cinemas and i highly doubt that they will film Eldest.
Before he moved to Los Angeles to pursue his dreams of acting, he attended Horizon High school in Phoenix, Arizona and began taking private acting classes which soon became his greatest passion.
