Nicolas Cage's Lavish Spending

Nicolas Cage once spent $276,000 on a 67-million-year-old dinosaur skull.

The 'National Treasure' actor - who has been forced to put several of his properties on the market after failing to pay millions of dollars of tax - filed a lawsuit in October claiming Samuel Levin, his former manager led him "down a path of financial ruin".

The 45-year-old American actor - whose films have grossed a collective $3.9 billion - owes $6 million in back taxes from 2007 and it is only now his extravagant purchases have come to light.

The most bizarre purchase was in 2007 when he outbid 'Titantic' actor Leonardo DiCaprio for a $276,000 skull claimed to be from a prehistoric beast.

He also owns a jet, two yachts, three castles, two islands in the Bahamas and a number of mansions.

His most expensive car - out of a fleet of 50 - was a $495,000 Lamborghini whose former owner was the shah of Iran.

Cage is a superhero fan - he had to sell his comic collection in 1997 for $1.6 million - and even named his son Kal-El, four, after the Man of Steel.
