There's one sequence in the TV spots, one that wasn't placed in the film
Roderick: "There will be no more eating of mankind."
Giants: *groans and complaints*
Roderick: "It's disgusting."
Wicke asks Roderick, after just pushing a soldier to his death, "Why do people always bother screaming before they die?" Seconds later, a giant reaches down, and snatches Wicke up, who screams until he's silenced by the giant's teeth.
Elmont: "Fear of heights?"
Jack: "Fear of falling."
Elmont: "Well then, don't fall."
Which is followed by this:
Jack: "Am I dead?"
Elmont: "Not just yet."
Elmont has many gems throughout the movie, but his best is his actor's near infamous line, "I have a bad feeling about this."
When Isabelle shows up at Jack's house, he recognizes her but doesn't identify her immediately. Instead, as they talk, he becomes very nervous and awkward. This leads to a moment where he accidentally sticks his finger in a candle and pauses in talking about his love of adventures to blow on them to help the pain.
