So, who is the better kisser? "Obviously I am," brags Tom. "I just answered that, and we'll move on to the next [question]. There's no argument."

"Yeah, let's get on with it, I don't want to fight it," smiles Chris.

As for prepping for those kissing scenes, Tom advises, "Altoids. You gotta have an Altoid. That's the standard form, yeah."

"I thought it was tuna sandwiches," replies Reese.

"That's like an immediate pre-game [strategy]," jests Chris. "Egg salad, onions."
