Movie star Jake Gyllenhaal was inspired to find fame and fortune, by his beetle-collecting great-great grandfather.

The Brokeback Mountain actor grew up hearing legends about his ancestry and is proud to reveal greatness runs in their family.

He says, "That's what I was told. He was a collector and cataloguer of beetles. We're interesting people. He was knighted by the King of Sweden and the Gyllenhaals even have their own coat of arms over there."
