Bana Talks About His "Cameo"

The Herald Sun in Australia posted a very brief summary of actor Eric Bana (Nero) current projects including Star Trek.

He described the role as a cameo. "It's just a great character, it's J.J. Abrams. It's a really well-written script, great part. Couldn't say no. I don't actually look at the size of parts ever."

I guess the villain of the movie doesn’t have much screen time. Not really sure what to make of the comment.
