Just a small sample from the spectacular new American musical, “La La Land.” By the way, the film was shot in CinemaScope using the same lenses — the exact same lenses — they used to shoot “Ben-Hur” in the late ’50s.

Music by Justin Hurwitz.

Correction: My cinematographer brother-in-law informs me that the “Ben-Hur” lenses were used on “Rogue One” not “La La Land.” My error. “La La Land was shot with regular Panavision 2X anamorphic lenses, the same format as CinemaScope originally, a 2X horizontally squeezed image onto the 4-perf 35mm film frame,” my brother-in-law says. He would know.
