Not a trailer but the full one minute animated zombie musical “Zombies4Kids” by Pedro Santasmarinas, produced by Anexo 82.
This one minute short teaches children how to survive an encounter with an undead. A unsettling premise that has been scoring great reviews and film festival selections worldwide.
The film was released in Portugal at the IndieLisboa Film Festival. It recently won the Premi Flash at the CIM-Sueca Festival in Valencia (Spain).
