Miller was born in Hoboken, New Jersey in September 1993. His mother is a modern dancer, and father a publisher. When he was 6-years-old, he performed in the U.S. premiere of Philip Glass’s contemporary opera White Raven and trained with the Metropolitain opera.

After his voice began to change, Ezra was kicked out of the opera in what he calls a traumatic but necessary transition into the other arts. Miller began his film career in 2008 with the Antonio Campos’s Afterschool, in which he played a teenager with a strange fetish at a boarding school. After that Miller appeared in City Island with Andy Garcia, Julianna Margulies and Steven Strait as a precocious chubby chaser. Miller also acted in Beware the Gonzo and Every Day – where he played a gay teenager with Liev Schreiber and Helen Hunt as his parents, both of which premiered at the Tribeca Film Festival. Miller next appeared in the BBC Films movie We Need to Talk About Kevin with John C. Reilly and Tilda Swinton, which was directed and adapted by Lynne Ramsay from American author Lionel Shriver’s 2003 novel of the same name. The film has become a Cannes Film Festival sensation and is already being tipped as a major contender for the Palme d’Or. Miller also acted as Damien on the Showtime’s hit comedy television program Californication. He appeared on Royal Pains as Tucker Bryant for two seasons. Ezra chooses gritty roles and will next be seen as gay teen Patrick in the movie adaptation of the coming of age novel The Perks of Being a Wallflower.
