Because jumping out planes is way more fun than CGI.
We’re only a few days away from the premiere of "Furious 7". What do we know about it so far? For starters (and most obviously), it’ll be the final screen appearance of actor Paul Walker. Early previews have all been extremely positive, and Vin Diesel himself has predicted it’ll win an Oscar for best picture next year. Fat chance, but we don’t doubt it’ll be a good movie within its genre. And as with all of the other films in the "Furious" franchise, there’s going to be a ridiculous amount of adrenaline pumping stunts.
Turns out the scene shown in the trailers with cars rolling out of an airborne plane isn’t CGI; it was actually done. Were the actors in the driver’s seats? No, but the required camera work was equally nuts. Check out this exclusive behind the scenes look at how the entire scene was filmed.
