According to TMZ, the National Treasure star bought the pyramid with the expectation that it will be his final resting place.
It is unclear how much Cage paid for the tomb or why he intends to use it as his gravesite.
The 46-year-old was recently ordered to pay East West Bank more than $2m (£1.29m). He also sold two historic New Orleans homes in a foreclosure auction because of his financial woes.
