The Lord of the Rings: The Two Towers (2002)

Continuity mistake: Gimli is lying with his face under the water, after jumping off the Deeping Wall and landing on the Uruk-hai. In the close-up, the right arm that grabs Gimli's shoulder to help him out of the water is Legolas' right arm. Yet, in the wide shot, suddenly it is Aragorn helping Gimli to his feet, not Legolas.

Gimli: Oh come on, we can take 'em.
Aragorn: It's a long way.
Gimli: Toss me.
Aragorn: What?
Gimli: I cannot jump the distance you'll have to toss me!...don't tell the elf.
Aragorn: Not a word.

Trivia: During post-production, one of the effects technicians had to transport the first effects shots to a special location, since their computer could not send them all the way to Peter Jackson. After storing them in his iPod, he walked out into the street and was targeted by two thugs. After some serious sprinting, he managed to reach a hotel and save WETA's visual effects from falling into criminal hands.

Question: I'm just curious, but at Helm's Deep, when Legolas says to Gimli "Shall I get you a box to stand on?" or words to that effect, was that line improvised by Orlando Bloom or was it in the script?
