Gabe Newell and J.J. Abrams discussing "either a Portal movie or a Half-Life movie"

Gabe Newell and director J.J. Abrams conversed on stage this morning at the D.I.C.E. (Design, Innovate, Communicate, Entertain) summit in Las Vegas. After a back-and-forth about player agency and storytelling (via Polygon's live blog ), Newell revealed that the duo had been "recapitulating a series of conversations going on," and that they're now ready to "do more than talk": Newell suggested "either a Portal movie or a Half-Life movie," and Abrams said he'd like to make a game with Valve.

Abrams is the currently reigning king of big franchise sci-fi filmmaking, taking his throne in the director's chair of both the Star Trek and Star Wars series. He's also known for producing Fringe, Cloverfield, and the maddening tale that was Lost.

In 2010, Newell told us that if Valve were to make a Half-Life movie, it wouldn't hand over control to any Hollywood studio, saying:

"There was a whole bunch of meetings with people from Hollywood. Directors down there wanted to make a Half-Life movie and stuff, so they'd bring in a writer or some talent agency would bring in writers, and they would pitch us on their story. And their stories were just so bad. I mean, brutally, the worst. Not understanding what made the game a good game, or what made the property an interesting thing for people to be a fan of.

"That's when we started saying 'Wow, the best thing we could ever do is to just not do this as a movie, or we'd have to make it ourselves.'"

There are no details on Newell and Abrams' project—be it game, film, or both—outside of the tease that they're talking. But they're talking, so how about some fun speculation? Who would you cast as Chell? Alyx Vance? Gordon Freeman? We love Bryan Cranston for the latter role, but he may have aged beyond Freeman. Is Hugh Laurie still a favorite?
