Jared Leto is one of the most committed and polarizing actors in Hollywood, a performer whose immersive approach to preparation has produced genuinely unsettling character work across a career that moves entirely on its own terms. He broke through with My So-Called Life (1994) and went on to a career that includes Requiem for a Dream (2000), Alexander (2004), and Dallas Buyers Club (2013), for which he won the Academy Award for Best Supporting Actor. His parallel life as the frontman of Thirty Seconds to Mars has run alongside his film career for two decades without diminishing either.

On screen, Leto disappears into roles at a cellular level, and the physical transformations he commits to, from the skeletal deterioration of Requiem for a Dream to dramatic weight shifts across multiple projects, are among the most discussed in the business. The angular face and eyes that shift from warmth to vacancy with unsettling speed give him a screen presence that is impossible to look away from, even when the material is uneven. He remains one of the few actors whose casting in a project immediately changes the conversation around it.
