Watson, 19, is devastated at the thought of not working with the cast and crewmembers of the hit franchise when shooting wraps next year, reports China Daily.
"I will be uncontrollable. It's been half of our lives. It's made us, it's formed us. It's such a big part of my life, so it will be really sad - and so much of the crew who have been there since the beginning are like my family," she said.
Though she has been working on the movies for over 10 years, Watson revealed that she does not socialise with her main co-stars Daniel Radcliffe and Rupert Grint off set.
"To be honest, we see so much of each other when we're working that hanging out together would be overload. I love them, but I need to see other friends off set. They're like my siblings now," she said to Interview magazine.
"We will always be very important to each other. But, at the same time, after eight 'Harry Potter' films, we'll be ready to go and do other things, and be other people, and have time for ourselves," she added. (ANI)
