The film stars Geoffrey Rush, Armie Hammer, Clémence Poésy, Tony Shalhoub, James Faulkner, and Sylvie Testud.

In Paris 1964, famed sculptor Alberto Giacometti bumps into his old friend James Lord, an American critic, and asks him to be a model for his latest portrait in his studio for a couple of days.

Lord is busy and needs to return to his work back home, though the chance to have his portrait done by Giacometti entices him to stay.

Giacometti's relationship with his wife oscillates between genuinely caring for her while requiring that he also have the freedoms implied by having an open marriage.

At one point she confronts him about being extravagant with his money when it comes to his models and courtesans, while at the same time being stingy about even buying her a coat.

He and Lord and the courtesan go out for a night on the town once her convertible arrives and when they get home, Giacometti finds that his studio has been ransacked.

As the portrait painting enter its final stages, Lord eventually departs for his office abroad and reflects on what to him was a first hand witnessed account of the artistic process of Giacometti's genius of artistry at work.

The website's critical consensus reads, ""Final Portrait finds writer-director Stanley Tucci patiently telling a quietly absorbing story, brought to life by a talented ensemble led by Geoffrey Rush and Armie Hammer.
