David Yates, who directed the film, revealed exactly what goes on on-set, on ABC Family.
David spoke about a scene in which Daniel, Emma and Rupert Grint have to run to avoid capture by Snatchers.
‘They run like maniacs and it’s because they are trying to out-compete each other.’ he revealed.
‘Dan wants to run faster than Emma. Emma wants to run faster than Dan and Rupert just wants to be anywhere to try to keep up with the pair of them’.
