While many celebrities are coming out of the woodwork to share their thrifty habits, one is admitting he’s already flown through much of his cash. Harry Potter and White Lotus star Jason Isaacs sits on an estimated $6 million fortune—though much of it might be gone.

“People will think I have huge stockpiles of money, but sadly, what I’ve done rather immaturely is expand my outgoings to match my incomings and pretty much spent everything I’ve earned over the years,” Isaacs told Vulture in a recent interview.

The British actor is estimated to have amassed millions from his incredibly successful roles: Lucius Malfoy in the Harry Potter series, which grossed over $7 billion worldwide; Colonel William Tavington in the $200 million box office hit The Patriot; the infamous Captain Hook in the 2003 Peter Pan; and more recently, Timothy Ratliff in HBO’s massively popular TV show The White Lotus.

Isaacs could have been even richer today—but it’s not just because he likes to spend

After his many successes, 62-year-old Issacs should be sitting on a fortune most actors would gawk at. But his bank account may not be as full as the other money-conscious celebrities who have accumulated a Hollywood nest egg.
