Nicolas Cage, 54, is known to have an eccentric taste

A hundred million dollars just doesn't last long when you're as eccentric as Nicolas Cage.

The 54-year-old actor has nurtured that reputation by amassing a collection of strange purchases that have nearly emptied his once-massive bank account.

Blockbusters like National Treasure and Ghost Rider once helped Cage be worth $150million, but a love for the unique has reduced the actor's fortune to around $25million, as told in the CNBC show The Filthy Rich Guide.

Much of the Oscar-winner's fortune went to buying expensive homes all over the world.

At one point Cage owned 15 homes that included a $25million waterfront mansion in Newport Beach, California, a $15.7million countryside estate in Newport, Rhode Island, and an $8.5 million pad in Las Vegas.

As if that weren't enough, the actor also bought two castles in Europe: One in Etzelwang, Germany, that cost him $2.3million in 2006, and another in Midford, England, that he got for a whopping $10million the following year.

Cage also got himself a deserted island in the Bahamas for $3million and the infamous LaLaurie mansion in New Orleans, which some say is one of the most haunted houses in the country.

His handling of his real estate investment was so poor that several of his properties went into foreclosure and he once had to pay the IRS $6.3 million in owed property taxes.

But some of the most bizarre purchases by the actor are one-of-a-kind, seemingly useless items.

Cage allegedly outbid Leonardo DiCaprio for a $276,000 70-million-year-old dinosaur skull

The actor also amassed a comic book collection worth $1.6million that included the first Superman comic, which he bought for $150,000

Shrunken pygmy heads, a nine-foot-tall burial tomb in New Orleans, a $150,000 pet octopus that he said helped his acting, and a $276,000 70-million-year-old dinosaur skull are just some of the extravagant things Cage has used his money for.

Cage reportedly outbid fellow big-spender Leonardo DiCaprio for the skull, but had to return it to the Mongolian government because it turned out to have been stolen.

Cage also has a love for fancy cars, and once owned nine Rolls Royces and spent $450,000 on the late shah of Iran's Lamborghini.

The star's former business partner once said Cage shopped 'uncontrollably' and needed a yearly paycheck of $30million just to sustain his lifestyle, The Telegraph reported.

Cage had sued Samuel Levin, claiming his former partner was to blame for risky investments that lead to 'catastrophic' losses and took him 'down a path toward financial ruin'.
