'Breaking Bad' star Bryan Cranston: The biggest money mistake I've ever made

"Breaking Bad" star Bryan Cranston nearly broke the bank after making a bad investment.

The actor, who is now worth millions of dollars, told CNBC that he tried to make it rich at a time when he was scraping to get by.

"I went into a business when I was a struggling actor," Cranston said on CNBC's "Closing Bell." "I bought a trampoline game — yeah trampolines."

The trampoline product turned out to be dangerous, in more ways than one.

"The insurance company said, 'They're breaking ankles.' So yeah it was a money-making idea that just turned upside down," Cranston said.

The investment "bounced me right out into the poor house," he said.
