Youssef Nosseir who calls himself the "Egyptian Harry" and who turned 20 this year with the film says its been a source of comfort for him over the years.
"When I want to run away from reality I just re-watch Harry Potter and it makes me feel safe," he said.
The event comes just over a week before the much anticipated cast reunion set to premiere on HBO Max on New Year's Day.
"They chose perfect time (to hold the event), it could be a coincidence but a good coincidence and it coincides in the same week almost as reunion week, so it's really exciting," said 28-year-old Mahinour Tawfik just after having her picture taken with an owl.
The day-long event ended with an outdoor screening of one of the films.
