Daniel Radcliffe, Emma Watson spice up Potter filming with on-set races

Actors Daniel Radcliffe and Emma Watson are said to have competed with one another on the set of ‘Harry Potter And The Deathly Hallows’ by trying to out run each other.

According to ABC News, the two, along with co-star Rupert Grint, were instructed by director David Yates to “run like maniacs” for a series of frantic scenes, and while they enjoyed it, Grint had to struggle to keep up.

“They run like maniacs and it’s because they are trying to out-compete each other,” the Daily Express quoted Yates as saying.

“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,” he said.

Grint added, “I didn’t realise it was going to be that fast actually, I was just keeping up with Dan and Emma.”

The first instalment of the two-part movie will be released later this year, while part two hits cinemas in 2011.
