The actor was channeling his inner rock star at the L.A. premiere Tuesday, rocking a black leather jacket with Bob Dylan pins, a fitted gray shirt -- and a killer 'stache, which is for his other new film, "Marty Supreme."

Timothée may be Hollywood’s heartthrob, but his leading ladies stole the show -- Elle Fanning and Monica Barbaro dropped jaws with their red carpet style.

Edward Norton and the rest of the star-studded cast also made sure to show up in style for the drama, which tracks Dylan’s rise to fame in 1960s NYC.

Timothée’s juggling a packed schedule, but right now it's all about plugging this biopic. He went all in, even taking guitar and vocal lessons to nail that signature Dylan sound -- and yes, he’s singing the tunes himself!
