EXCLUSIVE: Sam Littlefield has been cast as a shady character nicknamed Mouse in a recurring role on the new CW series Batwoman.

Littlefield’s character is described only as a “dynamic figure” who is “working for Alice and the Wonderland Gang,” which suggests that this Mouse might be going down a dangerous rabbit hole in Gotham’s underworld. In DC Comics, Alice is a mentally unstable threat to city and a mysterious figure with complicated past and a penchant for Lewis Carroll cosplay.

Alice will be played by Rachel Skarsten on Batwoman,
