I saw Christoph Waltz in business elite on the 777-200LR from LAX-ATL this morning. I was coming home from Perth (unfortunately in economy for all of my legs) so I was somewhat tired and it did take me a while to recognize him. Once I did recognize him my side of the aisle was already moving and I didnt get to stop and say hello or anything. And I was also seated on the 2nd to last row so I didn't get the chance to see him during deplaning either. Was pretty interesting to see him though, he is a great actor.
