Daniel Radcliffe and Emma Watson Race on the Harry Potter Set

In a recent trailer for Harry Potter and the Deathly Hallows, the infamous Harry Potter trio runs to avoid being captured. The reason they were running so fast wasn't just because of the script though: Director David Yates reveals that stars Daniel Radcliffe and Emma Watson were actually racing!

"Dan wants to run faster than Emma," says David. "Emma wants to run faster than Dan and Rupert [Grint] just wants to be anywhere to try to keep up with the pair of them."

Some friendly competition on set never hurt anyone!
