Where 'Girls' season 3 began with an appearance by a fan-favorite 'Orange Is the New Black' actress, the HBO dramedy is at it again. 'Orange' star Natasha Lyonne will break free of Litchfield to check in with Hannah on 'Girls' season 4, but as whom?

As was the case with previous 'Girls' season 4 castings, HBO wouldn't reveal much to TVLine, though we know that Lyonne's character goes by the name of "Rickey" and will appear at some point in the fourth season.

Elsewhere, we know of ‘Girls’ season 4 that production will likely return to the 10-episode format over season 3′s elevation to 12, while series star Andrew Rannells will enter season 4 promoted to series regular, and Adam Driver will remain a regular despite his ‘Star Wars‘ casting. We’ll also see Hannah undertaking the Iowa writers’ graduate school program that became a focus of the season 3 finale, despite the fact that the actual Iowa University denied Dunham the opportunity to film there.

'Community' star Gillian Jacobs will recur in a season 4 role, joining 'American Horror Story' and 'Heroes' veteran Zachary Quinto. Additionally, ‘Parenthood‘ star Jason Ritter will play a small part, while Marin Ireland of ‘Homeland,’ young filmmaker Desiree Akhavan and actor Peter Mark Kendall have been given recurring roles as fellow students in the writing program.

‘Girls’ season 4 won’t arrive until 2015, but in the meantime, what say you? Who else would you want to see bound for Brooklyn in the future?
