The first Fantastic Beasts premiered to more than $74,000,000 in its opening weekend and eventually passed more than $500,000,000 in worldwide box office, per Box Office Mojo.
Clearly, Fantastic Beasts has not had anywhere near the cultural footprint of Harry Potter.
That being said, the fact that the Harry Potter franchise in its current spinoff form is still trucking ahead and easily winning box office weekends while attracting tons of visitors to Universal Studios should not be discounted.
Barring a shocking dropoff, this opening too should be enough for the Wizarding World to barrel ahead.
