IFC Films has released the first trailer for Richard Linklater’s “Boyhood.”

Filmed over a 12-year span, the trailer shows the literal growth of now 19-year-old star Ellar Coltrane, who was just seven when filming started.

The coming-of-age story follows a brother and sister on their journey from childhood to adulthood. It also stars Ethan Hawke and Patricia Arquette as Coltrane’s parents.

“Boyhood” premiered to rave reviews at the Sundance Film Festival in January. Variety‘s Peter Debruge wrote that the “unprecedented experiment in long-term storytelling” — shot in three and four-day chunks — challenges the very notion of dramatic development.

Linklater won the Silver Bear for best director at the Berlin Film Festival.

“Boyhood” hits theaters on July 11.
