Cool!
I really liked this movie, and I thought it was funny how the narrator's voice was boring on purpose. When school starts, I will show this page to my science teacher, and I bet that my science class will end up watching the movie.
However, in many eukaryotic genes the introns are not useless, because the gene codes for a few different proteins. Sometimes different parts of pre - mRNA are spliced out (and an exon acts as an intron) to end up with a different protein.
Remember the beautiful Dscam gene in D. Melanogaster (fruit fly)?? It regulates the fruit fly's development, and there are 38,016 different splicing patterns. Isn't that cool?

"Diana is.... .... ..... ...ABSENT!!!!"
(meanwhile, a student steps through the doorway halfway as the bell finishes ringing)
Huh!? Oh yeah - I'm here - dont mark me as absent! PLEEEASE!?
"Fine. Half of you is here, so the other half gets detention for not being on time." (crickets chirping. Student stands frozen in the doorway for a minute) "Would the lagging half of you finish entering the classroom, please!?"
