Tom Hardy lost NZ$3.4 million making his new BBC1 drama Taboo.
The 39-year-old hunk created Taboo Productions Ltd to handle the finances for the eight-part series, which he wrote, produced and starred in.
But his first solo venture has transpired to be a financial flop.
A source said: "These new figures will make stark reading for Tom. No matter who you are or how much money you're worth, [$3.48 million] is a lot of money to simply throw away.
"This is the first major TV drama Tom has overseen himself. He has written it, produced it and starred in it, so he was always going to come up against some difficulties."
