6. Ashley Greene
Best known for appearing in the Twilight films (albeit with a terrible hair cut), Ashley Greene is a versatile actress who has appeared in numerous films over a relatively short career. But she has shown that she is not adverse to television as she appeared in the cancelled Pan Am television series. She's won awards although they are Teen Choice Awards. But if you want to attract a couple of distinct demographics to the Jessica Jones series, then you can't go wrong with Ashley Greene. Because if you're going to cast someone from Twilight, you might as well cast one of the ones who can actually act and I think Michael Sheen probably wouldn't be right for this part. She's 26, and one of the younger actresses on this list. She still looks fresh faced and would easily play flashbacks well. Greene would be a solid choice if the producers were looking for someone who was known and was in their twenties, but not someone who really has had a break out role yet.
