What a joy! It's M-G-M's Technicolor musical!

Jerry Mulligan is an exuberant American expatriate in Paris trying to make a reputation as a painter. His friend Adam is a struggling concert pianist who's a long time associate of a famous French singer, Henri Baurel. A lonely society woman, Milo Roberts, takes Jerry under her wing and supports him, but is interested in more than his art.
An American in Paris keeps every mind human — it fights its subject at zero distance. The story fights on E8 of the E0–E14 reality ladder, compressing love, art, culture, ambition, identity.
Films fighting at the same level of reality, about the same things.
The same preoccupations examined at another scale — one mind versus a nation.
