The film, an English language one from French director Arnaud Desplechin, made its premiere Saturday at the Cannes Film Festival, where it's among 20 movies competing for the prestigious Palme d'Or. In the genre of psychotherapy films — from Hitchcock's "Spellbound" to David Cronenberg's "A Dangerous Method" — "Jimmy P." is particularly faithful to the probing dialogue between patient and analyst. Desplechin said he wanted to grasp "the adventure" between the pair as they become friends while sifting Jimmy's memories for the roots of his pain. [...] he said, the film is ultimately about a transitional kind of nationality, and the friendship that blooms between a discriminated-against Native American and an immigrant doctor, both finding their way in a country foreign to them.
