Sources tell THR that Walker's character, Brian O'Conner, will not be killed off in the film, now set for release April 10, 2015. Instead, the plan is to "retire" the character in a way that the studio hopes will satisfy fans of the franchise and make use of the existing footage of Walker, who died about halfway through the Fast 7 shoot.
In the weeks after the tragedy, director James Wan, writer Chris Morgan and Jeffrey Kirschenbaum, Universal's lead executive on the Fast films, pored over the footage Wan had shot. The trio then devised a plan to tweak the existing script so that Walker would remain a part of the story but could be written out, allowing the franchise to continue without him.
The changes will require some additional scenes to be written and shot, but the eight-month delay of release provides plenty of time.

Well, at least something, right? If they killed him... I don't think I would be able to handle that. But, to be honest, I'm not even looking forward to the movie - actually, the franchise as a whole pretty much lost my interest. For me, Paul Walker and his Brian O'Conner WERE the franchise. I loved FF because of BOTH Dom and Brian, because of their friendship. I don't really care about Dom by himself or about Letty or Mia or Hobbs or... or that guy from FF3. Yes, the movies are about the Toretto family - but for me, Brian was the heart of it. Now...
And... I'm depressed again. Fuck. I wonder when I will finally be able to read a mention of Paul Walker without tears immediately stinging my eyes...
