It's been talked about for a while now, but at the Screen Actor's Guild 25th-anniversary reunion, Stephen Cannell confirmed that a film version of The Greatest American Hero was on its way. SCI FI Wire reports that there was a Q&A session featuring the cast and crew of the original series, where Cannell confirmed information about the film.

"We've written a screenplay, and we've hired a director, and we're in the midst of putting this together for the future." Cannell said. At that panel, Connie Sellecca (who was a part of the original series), asked if there would be cameo roles for her, William Katt and Robert Culp. "Absolutely guaranteed," Cannell responded. "More than cameos: acting jobs."

"I took a sneak peak at the [feature] script, and it's absolutely charming and wonderful," Katt told the rapt audience. "I know people are going to love it."

The director for The Greatest American Hero is reportedly Stephen Herek, though Cannell did not confirm this during the panel.

Originally a television series on ABC, The Greatest American Hero ran for three seasons and it still holds a soft spot in the hearts of many fans. Katt starred as Ralph Hinkley, a teacher who gains possession of a red alien suit that grants superpowers - although he does not get the instruction manual. Culp also starred as Hinkley's FBI minder, Bill Maxwell, and Sellecca portrayed Pam Davidson, Ralph's long-suffering girlfriend.

Interest in the series is riding high at the moment, with the announcement of the film, as well as a new series of comics produced by Katt under the Catastrophic Comics banner. In addition, there are plans for a series of animated shorts to be voiced by Katt, Culp and Sellecca.

"The cast all felt--and I think the writers as well--[that] we had stories left to tell, and so that's what we're doing," Katt said. "We're picking up where we left off, and I know that there's a great audience out there that is going to be receptive to that." He added, "In the public arena, at Comic-Con and other [conventions] out there, we've found that there is a tremendous warm welcome still left waiting for The Greatest American Hero."
