In comparison with other earlier blockbusters, the final “Harry Potter” film was seen in 3-D by a smaller proportion of North American viewers – below half, roughly 43 percent, says Dergarabedian.
“Europeans are higher on 3-D,” he notes, saying that even with the big “Transformers” blockbuster – which nearly 60 percent of Americans experienced in 3-D – “overseas the number was more like 70 percent.”
