Who does the voice for the Cheshire Cat in Alice Madness Returns

Roger Jackson

GFM: Will the original voice of Alice return?
AM: Of course! Alice wouldn't be Alice without Susie Brann (the voice actress who played her in the first game). She and Roger Jackson (Cheshire Cat and more) are both reprising their roles with RJ Berg writing their lines and directing their VO sessions.
