Did run a quick search, Zoe's movies have outgrossed Urbans, but if you subtract Avatar her grosses worldwide fall to about $1 billion. $654 million of that is Pirates of the Caribbean. All her other movies made $400 milliom or so. Subtract BOTH LOTR movies and Urban's total is slightly higher than Saldana's without Avatar. Plus I think her roles were smaller in her earlier movies than Urban, who can easily headline his own movie.
