WATCH: Natalie Portman on the Differences Between People in L.A. and Paris

Natalie Portman has a fondness for the Parisian lifestyle, but she says people in L.A. are much friendlier.

Appearing on Jimmy Kimmel Live! Thursday night (Aug. 25), the actress told Kimmel, “Everyone smiles a lot here — it’s very nice. They’re very cool in France.”

She recalls the warmer feelings when she moved back to the City of Angels. “I got here and I was so surprised when you get in an elevator and someone starts a conversation… or someone would smile at my child.” Portman and husband Benjamin Millepied, who is French, have a son, Aleph, 5.

Portman also explained how it works shopping in Paris. “There’s a lot of rules of politeness and codes of behavior there that you have to follow. When you go in some place, you have to say ‘Bonjour’ before you say anything else, and then you have to wait two seconds before you say anything else.”

She added that if you do not follow this protocol, “They’ll think you’re super rude and then they’ll be rude to you.” Watch the whole interview above!

Portman recently directed and starred in the biopic A Tale of Love and Darkness, set against the backdrop of the end of the British Mandate for Palestine and the early years of the State of Israel.
