The two Harvard grads who gave us “La La Land’’ — Damien Chazelle and Justin Hurwitz — were among the VIPs who walked the red carpet Tuesday night at the AFI Fest gala screening of the musical at the TCL Chinese Theatre in Hollywood. Chazelle wrote and directed “La La Land,’’ and Hurwitz composed the music.

They were joined by actress Emma Stone (who plays Mia in the film), costume designer Mary Zophres, choreographer Mandy Moore, andproducers Jordan Horowitz, Gary Gilbert, and Marc Platt.
