Late-teen female, independent, good sense of humour, fit.
Young twenty-something male, witty and smart, fit but not traditionally good looking.
A late twentysomething male, fit, handsome and confident.
Seventy-something male, with strong opinions and tough demeanour. Also doesn’ t need to be particularly fit.
A second young female, also late teens, tough, smart and fit.
Forty something male, fit, military type.
Thirtysomething male, intellectual. Apparently doesn’t need to be fit.
What can we conclude from this? Well, very little, but it does lend itself to wild speculation. There have been rumours that Michael Arndt's script has a female protagonist, which this does not contradict - although Bleeding Cool, who originally picked up the call, notes that this is not necessarily credit order, so that first role doesn't necessarily correspond to Luke Skywalker.
The calls for a cast that is largely "fit" makes it a safe call that there will be action, in case that were ever in doubt, and while we're wildly speculating it looks like any romance will be between very young women and slightly older men. There's no mention of prosthetics or performance capture here, so for the moment let's assume that these people are all playing human-looking beings rather than more alien / droid types.
What else can you glean from these brief descriptions? And who do you think would fit? Let us know in the comments below.
