Guillermo del Toro ayaa ku dhawaad diyaariyay filimkiisa cusub oo soo saare ah "Ha ka baqin mugdiga", kaas oo ay jileyso aktarada Katie Holmes, ka dib markii ay jishay filimkeeda.
Qorshuhu ma aha mid aad u asal ah maxaa yeelay waa sheeko ku saabsan guri dablay ah. Haweeney ayaa aabbaheed u guuraysa guriga ayeeyadeed. Halkaas ayay ku ogaan doonaan in gurigu xidhiidh la yaab leh la leeyahay nolosha dambe.
In kasta oo trailer -kii ugu horreeyay durba la heli karo illaa xagaaga 2011, ma awoodi doonno inaan ku aragno filimka "Ha ka baqin mugdiga" ee tiyaatarada.
