HARRY POTTER villain JASON ISAACS is hiding an embarrassing secret – he’s a terrible swimmer who once had to be rescued from drowning.

The Brit filmed Peter Pan on location in Australia in 2003 and convinced co-stars he was eager to hit the country’s famous beaches.

But he is such a poor swimmer he had to be rescued by a lifeguard – and was secretly relieved when movie bosses banned him from the water.

He tells Total Film magazine, “I pretended that I was incredibly upset but the truth is I’m a terrible swimmer.

“One day I had to be rescued by the lifeguard in front of all these beauties. As I was carried back out the waves like some helpless three-year-old. I tried to hide my head in shame.”
