"We are growing up on screen," said Jamie Flatters, who plays Neteyam. "I'm just extremely grateful to be part of this."

"I was so proud," said Bailey Bass, who plays Tsireya. "I was very interested to see 13-,14-,15-year-old Bailey, how I acted then and how that would be received."

Trinity Jo-Li Bliss is only 13-years-old now. She was born in the same year that the first Avatar film was released.
