Speaker for the Dead Resources
This is what the title says it is: Card's official web place. It includes video interviews, news and reviews, writing lessons, essays by Card, and lots of other things OSC.
A user-created encyclopedia of all things Orson Scott Card, including lots and lots of entries on Speaker for the Dead. Again, it's user-created, so you want to be careful to double-check the info, but it's a great resource.
Movie or TV Productions
Though Ender's Game was adapted into a 2013 movie, there are no plans to film Speaker of the Dead. Card himself has said "'Speaker for the Dead' is unfilmable. It consists of talking heads, interrupted by moments of excruciating and unwatchable violence […] I don't want it to be filmed. I can't imagine it being filmed.'"
So, he isn't going to greenlight a film adaptation, is what Shmoop takes away from that.
