Ringer Simon wrote in last night about a couple of competitions to win tickets to the World Premiere of RotK for Australians. Now he has a few tiny dialogue spoilers from the KFC ad:

I finally paid attention to that KFC/RotK promo ad, and wrote down the Frodo/Sam dialogue. Here it is:

Frodo: (to Sam) “Not without a guard… I need you on my side!”
Sam: (to Frodo) “I am on your side, Mr. Frodo.”

Plus I think Gollum might be in the scene as well, but he doesn’t say anything at that point.
