The team at Weta Digital, the video effects studio that worked on The Lord of the Rings films and other CGI-filled epics, had their toughest assignment ever last year: finishing Furious 7 without the film's lead actor, Paul Walker, who passed away in a car crash on November 30, 2013. Their work was widely lauded, and the film's final scene pretty much made the whole planet cry. Now, thanks to new interviews and the work of some very patient Internet sleuths, the past week has brought the web a much better understanding of just how big this accomplishment was.
