I'm glad I wasn't the only one who thought of this. I didn't even know there was a film with the same name 0.o
Well, I can't find it on Wikipedia. Basically, it starts out with this kid, whose name I can't remember, using a remote-controlled helicopter with birds on it to fly in front of a security camera so the kid can go by unnoticed before returning to the institute where he's working on making stuff invisible. Later it's discovered his dad died in a car crash, who, if I recall correctly, was a spy, because he was being chased by people. Eventually, the kid meets a girl named Alis, whose name is later found to be actually Sarah, but her and her family are trying their hardest not to get noticed because bad people are after them. The kid ends up getting his uncle Cutter's help and discovers that his friend Barney was a spy. If anyone can find it, I'll love you forever.
