 Alby Ojeda and Juanjo Ramírez decided to work at the movies when  they saw Terry Gilliams "Twelve monkeys". Ten years later, they  make Going Nuts (their first long movie) and they dont realize that  they are making a movie about crazy people in a mental asylum, just  like "Twelve monkeys". Thats the reason why Terry Gilliam is given  thanks at the end tittles of Going Nuts.
