9.Mel Gibson

An actor who gained worldwide fame thanks to his acting credit in the Mad Max films, Braveheart, and the Lethal Weapon movies, Mel Gibson has shown that he still has a few tricks up his filmmaking sleeves with the 2016 biopic Hacksaw Ridge.

Through the years, Mel Gibson’s acting and filmmaking career has helped him gain a fortune – and it’s a fortune that only seems to keep growing with time. Perhaps one of the most expensive purchases the actor made was his very own private island, Mago. Besides his private island, Mel Gibson has a collection of world-class and relatively modest cars in his garage, including a Mercedes Benz ML320, a 1990 Lexus LS400, a Bentley Arnage, and a 2008 Maserati Quattroporte.
