It looks like Alden Ehrenreich will be the Young Han Solo in a standalone film.  It was revealed at the Star Wars Celebration event in London.

The audition took about six months, including doing multiple screen tests alongside Chewbacca.  Ironically enough, he was the first actor that the directors saw for the role.

The 26 year old actor is known for his role in Hail, Caesar! and Beautiful Creatures.
