The first one comes via Lezbehonest. It's amazing:
Grant Wilfley Casting is seeking an African American boy, 9-12 years old, with very dark skin tone to be a featured extra in the Disney film “The Sorcerer’s Apprentice” starring Nicolas Cage. We are specifically trying to find a boy with dreadlocks but may be able to do a wig if we find the right boy who doesn’t have dreads. The most important part of this is a boy who is not afraid of snakes. There will lots of real snakes in the scene & the boy will be required to hold 1 or 2 of them. The snakes are well trained, non venomous and there will be several animal trainers on set the entire time to ensure safety. But this will obviously require a boy who is unafraid of snakes.
Which reminded me of this incredible Harper's Readings clip of the real casting notice for Christina Aguilera's Beautiful video.
