Ars Technica has details from today's D.I.C.E. Summit keynote by Valve's Gabe Newell and Hollywood's J.J. Abrams where one of the topics was a game/movie collaboration. At one point Abrams says he has an "idea for a game that we'd like to work with Valve on" which inspired the following response from Newell: "We're also interested in working with you guys on movies. We're going to see if we can make a Portal movie or a Half-Life movie."
