Julianne Moore had to change her name. No, it wasn't to hide her Jewishness; she is not exactly Jewish. It was to hide her commonness.

Moore's real name is Julie Smith. Unfortunately, Hollywood already had a bunch of Julie Smiths. She couldn't even go by her full name, Julie Anne Smith, as that was taken already. So she made her names into a portmanteau, slammed her father's middle name Moore on, and came up with Julianne Moore.

Now, "Moore" is no "Smith", but it's still a tad common, isn't it? Here's what she should have done: not stop at her father. Go back a few generations, to her Jewish great-great-grandfather, and use HIS name. That would have made her...

Julie Hamburger.

Alright, maybe she made the right choice...
