Mr Moist on Instagram: "Insane The Batmobile jump in Batman Begins was done as a real, practical stunt using a full-size Tumbler weighing around 2.5 tons. Built as a fully drivable vehicle under Christopher Nolan and production designer Nathan Crowley, multiple Tumblers were constructed for different stunts. For the Batcave waterfall jump, the effects team used a hidden nitrogen cannon to launch the car off a ramp—minimising CGI and giving the scene its raw, physical impact."
