Marissa: I don't know. Russell Crowe, he just doesn't do anything for me. I mean people say he's good looking but I don't see it.
Marissa and Ryan are discussing the movie they have just finished watching, Master and Commander: The Far Side of the World starring Russell Crowe.
Russell Crowe, at the time, is one of the biggest movie stars around. Along with numerous awards and nominations, he most notably has been nominated for 3 Academy Awards (Oscars) for Best Actor, winning one of them.
This quote is also an inside joke because most people believe Benjamin McKenzie resembles a "young" Russell Crowe.
