Lucky for Moore, many of Gibsons movies were mega hits including “Lethal Weapon” and “Braveheart.” They have earned him huge royalty checks every year with “Passion of the Christ” which Gibson self-financed grossing over 600 million internationally. Among his real estate investments, Gibson also owned a church in Malibu and his own private island in Fiji.
