John Wesley Shipp, who played Barry Allen/the Flash in the titular 1990s live-action CBS program, will have a mysterious role in the CW and Warner Bros. Television’s pilot of the same name.

While exact details of the part are being kept under wraps, the CW did say that it is intended to be a recurring guest star if the “Arrow” spinoff is picked up to series.

Grant Gustin plays Barry Allen in the reboot, which is based on the DC Comics characters. Other stars include Candice Patton, Rick Cosnett, Danielle Panabaker, Carlos Valdes, Tom Cavanagh and Jesse L. Martin.

Pilot is penned by Greg Berlanti, Andrew Kreisberg and Geoff Johns and directed by David Nutter. Berlanti, Kreisberg and Nutter are exec producing; Melissa Kellner Berman is co-exec producing.
