Multiple Harry Potter actors were in also attendance, including Emma Watson, Evanna Lynch, Katie Leung, Jim Broadbent, and Jason Isaacs. Some photos and videos can be seen on Empire's official website here.
Thanks to Raadhika from The Daily Snitcher, who sent in pictures of Yates and the actors and actresses.
The awards will be broadcast in the UK on ITV2 tonight (March 10th) at 9:00 pm.
UPDATE: Thanks to TLC for letting us know of a new video interview with director David Yates at last night's Empire Awards, where he mentions talks of him directing the Deathly Hallows movie and that he's definitely "tempted."
