Seeing Joan of Arc today remains a cinematic revelation, its approach to storytelling, set design, editing, and especially cinematography (by Rudolph Mate, who also shot Dreyer's visionary Vampyr) radical then, and still strikingly modern many decades later. Influenced by both German expressionist film and the French avant-garde, Dreyer's huge set was designed with asymmetrical doors, windows, and arches, through which Mate's camera moves along equally off-centered, even vertiginous, but fluid trajectories. Although the story is epic in its implications, the film is composed primarily of extreme close-ups, especially of Joan and her principal interrogator, Bishop Cauchon, and medium shots of small groups, often shot from low angles. Dreyer and Mate shot their cast in bright light, without makeup, giving each wrinkle, blemish, or tuft of hair sculptural detail.

For all its visual invention, however, Dreyer's film is most devastating in its central performance by Falconetti (nee Renee Falconetti), a French stage actress who made her only screen appearance here--one critic Pauline Kael has suggested "may be the finest performance ever recorded on film." Through Falconetti, Joan's spiritual devotion, simple dignity, and suffering become utterly real; even without a dialogue track and only sparse inter-titles, the film achieves a fevered eloquence.
