Miller, was senior vice president and managing director of Walt Disney Company's adult book publishing division, Hyperion Books, and is a publisher at Workman Publishing. He has two older sisters, Saiya and Caitlin. Miller considers himself Jewish and "spiritual".
Miller was trained as a singer, and has sung with the Metropolitan Opera. When he was six, he performed in the U.S. premiere of Philip Glass’s contemporary opera White Raven. He attended The Hudson School, dropping out at sixteen.
Miller began his film career in 2008 with the Antonio Campos’s Afterschool, in which he played a teenager at a boarding school. After that, Miller appeared in City Island (2009), with Andy Garcia, Julianna Margulies, and Steven Strait, and co-starred in Beware the Gonzo and Every Day, both of which premiered at the Tribeca Film Festival. In the latter film, he played a gay teenager with Liev Schreiber and Helen Hunt as his parents. 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 became a Cannes Film Festival sensation, winning critical acclaim. 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. He is confirmed to play Patrick in the movie adaptation of the novel The Perks of Being a Wallflower.
Miller is a drummer and a singer in a New York-based band called Sons of an Illustrious Father.
On June 28, 2011, in Pittsburgh, Pennsylvania, where he was shooting The Perks of Being a Wallflower, Miller was a passenger in a vehicle that was pulled over for a broken brake light and police discovered that he had 20 grams of marijuana in his obsession. He was initially charged with drug possession but the charge was later dropped by a judge. Instead of these charges, Miller faced a penalty of $600 for two citations of disorderly conduct. Miller later commented:“I don’t feel like there’s any need to hide the fact that I smoke pot. It’s a harmless herbal substance that increases sensory appreciation.”
