Marvel and FX have just released their first look at the upcoming series Legion, based on X-Men comic character David Haller.

Downton Abbey star Dan Stevens is shown as Haller, the son of X-Men founder Professor Charles Xavier.

Haller will first appear as a young man struggling with mental illness, diagnosed with schizophrenia and having been in and out of psychiatric hospitals for years.

Eventually, he realises the voices and visions in his head might be real.


In the comics, Haller does actually have a kind of split personality disorder and each of his hundreds of personas controls different aspects of his powers.

His personalities range across a broad spectrum of characters from terrorist leader to obese woman to British punk rocker to pirate - and those are just the human ones.

Legion will run for an eight-episode first season debuting in early 2017 on FX in the US.
