Trailer

Monster Family follows the very much unhappy Wishbone clan, Frank, Emma and their kids Max and Fay - under pressure and constantly at each other's throats. When they are cursed by an evil witch and transformed into their own monstrous party costumes, they must pull together to battle real-life beasts; reverse the curse; and prove that even a vampire, a mummy, a werewolf, and Frankenstein's monster can eventually form one big happy family.
