Only ONE thing missing from the film...
I would have liked to have seen this;
As the credits start on the screen, Gru pulls the black background up and says; "HOLD IT, everyone! We have ONE last bit of unfinished business!..."
Then we cut to the orphanage and we see that the minions have locked the cruel orphanage head inside the box of shame and are tormenting her while she pleads to be let out!
