If one is of the opinion that Julie Delpy is a delight, which is very much the correct opinion to have if one is an open-hearted person rightly familiar with her flirty, thoughtful collaborations with Richard Linklater and Ethan Hawke, as well as 2 Days in Paris, then the trailer for the latter’s sequel, 2 Days in New York (Magnolia, August 10), co-starring Chris Rock, will bring a smile to your face, if only for the deliciously oddball pairing it seemingly augurs. Cultural differences, unwitting racism and uncomfortable sexual candor get a comedic workout in this tale of a radio deejay and the visiting family of his live-in French girlfriend. Again, the trailer is here for those wishing to take a gander.
