From IMDB:

A jazz pianist falls for an aspiring actress in Los Angeles.

From the moment all the drivers in an LA car jam leave their autos and start singing and dancing I was hooked.  Probably this means you will either love or hate this film which is in some way a throwback to such Gene Kelly films as “Singin’ In The Rain” or “An American In Paris”. In fact the last time I can remember the actors in a scene breaking into song was the unexpected moment in “My Best Friend’s Wedding” in the restaurant when the cast joined in singing “I Say a Little Prayer For You”. Of course the characters sing in musicals, but I am not sure you can call this film a musical. Give the film an A for originality because it is almost sui generis.

Adding to the enjoyment was the clever and swift changes from scene to scene, the unexpected time sequence changes, to say nothing of the clever but surprising ending.

Hats off to Ryan Gosling as Sebastian and Emma stone as Mia.  As a pair they have appeared together in several films. Ryan had to learn tap dancing and piano for his role because no piano hand models were used.  On the Internet you will find many articles about how much they rehearsed.

Ryan Gosling (age 36 during filming) is one of my favorite chameleons. For example he has played the following: Hercules; a young prosecutor matching wits with Anthony Hopkins in “Fracture”;   a delusional man in “Lars and the Real Girl”;  a sociopathic killer in “All Good Things”;  and a motorcycle stunt driver in “The Place Beyond the Pines”.

Possibly destined to be a classic. DO NOT MISS!
