Was in Star Wars

She had a small part in Star Wars Episode II: Attack of the Clones as on of Senator Amidala's handmaidens. She played Dormé. Doesn't surprise me, she's pretty enough.

You see her in at least four scenes (one of them you need sharp eyes for). She was in the background when Padmé was talking to Obi Wan and Anakin in her apartment, discussing security until they could find the assassin. The second scene was when Padmé almost got bitten by one of the worms Zam Wessel put into her apartment. You see her coming in and asking Padmé if she's okay. The third was when Padmé was packing her clothes to leave Coruscant and go into hiding.

The last scene Dormé was in is most noteworthy, because in that one, Padmé was saying goodbye to her before leaving the capital, and once again, even as a Senator, Padmé was still employing that trick from her Queen days of having handmaidens pretend to be her when she couldn't be in her main role, due to security concerns. Truth be told, Rose Byrne doesn't look quite like Natalie Portman, but her character looked enough like her to possibly fool some people, so long as she didn't do any heavy political work in her mistress's place.
