Actually, I believe that might be Emma Watson. Harry Potter and the Half-blood Prince grossed a billion dollars US....
...beaten only by Zoe Saldana as Naytiri te Tskaha Mo'at'ite, princess of the Omaticaya, grossing $US 1.3 billion in 2009.
Zoe = the Lysacek of filmdom.
Yes, it was Emma Watson. I think she's the highest-grossing actress of the whole decade. But her Harry Potter cohorts were beat out for highest-grossing actor of the decade by a guy who co-starred in TWO huge franchises--Orlando Bloom. (Since he's near the top of my non-skating swoon list, I can't complain.)
I don't know what the skating equivalent would be. Someone who won both Worlds and Olympics every year?
