Star Wars: The Force Awakens - 10 Things We Need To See In The Next Trailer
3. Lightsaber Action
In terms of the teaser trailers, we have only seen one ignited lightsaber: the broadsaber of Kylo Ren, with its rough, angry, home-made aesthetic. It may be slightly divisive, but it's certainly memorable. We also saw Luke's old lightsaber being passed from one hand to another, and Star Wars released a brief clip on Instragram that, right at the very end, showed Finn holding that very same weapon, looking ready to fight.
Clearly the idea it's setting up is that Finn will be duelling with Kylo Ren, but that could simply be a huge case of Abrams doing his best to mislead us. It wouldn't be the first time (and rumours certainly back that up). I don't actually want to see whether that's true or not until the film, but some clashing lightsaber action would be awesome.
They don't need to show the characters, just have a shot of the red against the blue.
