A comic book created and co-written by the actor Keanu Reeves arrives in stores on Wednesday, with more than 615,000 copies ordered by comic book retailers. (The order is notably high: Last March, Marvel released a new Spider-Woman No. 1 that sold 142,000 copies in North America, according to Comichron.)

The comic, BRZRKR (pronounced “berserker”), is about an immortal warrior, with a look inspired by Reeves, on a quest to discover his origin and to end his long, 80,000-plus-year life.

BRZRKR, from Boom! Studios, is co-written by Matt Kindt and drawn by Ron Garney. “I’ve loved comics since I was a kid and they’ve been a significant influence artistically throughout my career,” Reeves said in a video interview for Boom! posted in January. The series will run for 12 issues.

Boom! had a good inkling of interest for the book last year. In September, the company ran a Kickstarter for supporters to pre-order collected editions of the comic. The campaign had a goal of $50,000 and ended at $1.45 million. The first volume is due in October. (Excellent.)
