"Looking" and "Hamilton" star Jonathan Groff has joined "Mind Hunter," David Fincher's upcoming Netflix crime-drama.

According to TVLine, Groff will appear in a series-regular role, which has yet to be specified.

The upcoming show is based on the 1996 non-fiction book "Mind Hunter: Inside the FBI's Elite Serial Crime Unit" by John Douglas and Mark Olshaker, which follows Douglas' time on the FBI's serial crime unit, investigating notorious killer and rapists.

David Fincher is directing the first episode, and also producing, alongside Charlize Theron.
