While we’ll never see David Haller and his company of subversively-powered ‘mutant’ allies join forces with his alledged father and his students in the current X-Men or Gifted timelines it does mean that they can use locations and clothes from those franchises.
At SDCC17 Dan Stevens said:
“There’s some cool outfits that we haven’t seen; there’s some hair that we’ve got to work up to; there’s also some locations…”
We only hope that means David’s recognisable pointy hair style will start to make an appearance at some point in the series.
“There’s also some locations… there’s some stuff in Tibet in the comics, I wouldn’t be adverse to it.”
How Tibet factors in to series when the current location of his activities is nebulous and undefined is curious.
Legion season 2 airs 2018.
