Natalie Portman impressed everyone on the Berlin set of her latest film "V For Vendetta" when she started conversing in fluent German.

Unlike many actors, who would be silenced by the language barrier, the "Star Wars" actress, 23, immediately started communicating in German.

"She just turned up one day talking German. It has made her very popular with the Germans on the crew," a source was quoted as saying.

Educated at the US's top Harvard university, Natalie is reportedly fluent in Hebrew, French, Japanese as well as German.

"V For Vendetta" explores how different life would be if Germany had won World War II.
