The network revealed that production had officially kicked off while sharing an Instagram snap of Rose and Theo as artist Clare Abshire and librarian Henry DeTamble.

The show is based on the 2003 Audrey Niffenegger novel, The Time Traveler’s Wife, a story about a married couple who deal with time travel in their romance.

In the photo the duo were seen cozying up on a leather couch while engaging in conversation. From the looks of the snap it was unclear if they were actually in scene, or sharing a laugh in between takes while in full costume.

The network described the upcoming series as an ‘intricate and magical love story,’ which has been adapted by executive producer Steven Moffat (Sherlock, Doctor Who) and director David Nutter (Game Of Thrones).
