The May issue of Enterbrain's B's-Log game magazine announced on Saturday that QuinRose's Alice in the Country of Hearts (Heart no Kuni no Alice ~Wonderful Wonder World~) fantasy romance adventure game is being adapted into a theatrical anime film. The game for female players (otome game) re-imagines Lewis Carroll's classic fantasy novel Alice's Adventures in Wonderland with bishōnen characters. (The game's Japanese title is a wordplay on that novel's Japanese title, except it replaces "Fushigi/Wonder" with "Heart.")

The game first shipped for Microsoft Windows in 2007, and the Prototype company ported it to the Sony PlayStation 2 game console in 2008 with new computer graphics and new story elements. (Prototype's PSP version followed in 2009.) Two more games called Clover no Kuni no Alice (Alice in the Country of Clovers) Joker no Kuni no Alice (Alice in the Country of the Joker) debuted in 2007 and 2009, respectively.

An original video anime adaptation was already planned in 2008, but it has been delayed since that year. Soumei Hoshino adapted the game into a manga in Mag Garden's Monthly Comic Avarus magazine until last September, and Tokyopop published the fifth manga volume in North America last November.
