Zachary Quinto To Boldly Go Into Girls Cast

Playing Mr Spock in the rebooted Star Trek movies has seen Zachary Quinto risking his life in defence of civilisation and boldly going into distant galaxies.

However the 37-year-old star will be facing his most terrifying challenge yet when he makes a guest appearance in the next series of hit HBO comedy-drama Girls.

The Hollywood star will be joining creator and lead actress Lena Dunham - seemingly as a workmate of her self-absorbed character Hannah Horvath.

The pair were spotted together as filming took place in Brooklyn this week - wearing matching blue smocks with the words "Ask me my name" on the front.

Unfortunately fans will have to wait until early 2015 to find out what happens to Hannah and her messed-up mates following the dramatic events of the last season finale.
