Tportal is reporting that Rade Serbedzija has completed his first scenes as Wandmaker Gregorovitch for Harry Potter and the Deathly Hallows. A rough translation says:

Mr. Serbedzija says that he has one scene with acclaimed actor Ralph Fiennes (Lord Voldemort) and praised the actor calling him “amazing.” He also said that meeting with actors Dan Radcliffe, Rupert Grint and Tom Felton was fun as they joked and called him “Boris the Blade” in reference to his character in the film “Snatch.”

Thanks TLC!
