Movies directed by their stars are a genre unto themselves, one that includes first-person documentaries, avant-garde “psychodramas,” and self-portraits like Jeanne Moreau’s “Lumière” — a movie about a fictional actress in her prime.

“Lumière,” Moreau’s first film as a director, is showing for a week at Film Forum, starting March 17, newly restored and seven minutes longer than the 1976 version released in the United States.
