Too Bad Katie Cassidy Isn't Related To Hopalong Cassidy, A Whiz In Showbiz

Katie Cassidy got the show biz gene from her dad, David Cassidy, a 1970s teen idol and her grandfather, suave actor Jack Cassidy.

But the 26-year-old actress has to spout legal lingo as a lawyer on the CW series "Arrow" and she feels she doesn't hit the mark. "It doesn't come naturally. It's a muscle you have to exercise," she complains.

Cassidy added, "As a lawyer, you're almost on stage. For me, I walk into the courtroom to interrupt a case, and everybody turns and looks at me, and I give this whole spiel. (In real life,) it's probably really, really intimidating."
