Roland Klick - Bübchen AKA Little Boy [+Extras] (1968)

"Buebchen" is the german word for "Little Boy". The film was also released under the title "Little Vampire" which doesn't make any sense at all.
 
A strange case baffles the police and the citizens of a German small town. A two-year old girl has disappeared. There are suspects, innocents, guilty ones and a web of lies.
It's saturday afternoon, and Achim's parents are invited for a topping-out ceremony. The neighbour's daughter, Monika (Renate Roland), is the babysitter for Achim (Sascha Urchs) and his little sister Kathrin, but Monika doesn't take the job too serious. She'd rather go for a ride with her boyfriend. Through a unforeseen row of circumstances, Achim becomes the murderer of his sister, and hides the body in a wrecked car on the scrapyard. When the parents return home, a frantic search for the little child begins. Only the father (Sieghardt Rupp) seems to know the truth.

Director Roland Klick (who turned down an offer to helm Christiane F. - We Children From Bahnhof Zoo) got the idea for his feature-length debut - originally planned as a black & white film - from a little note in the newspapers, and needed only 16 hours to write down the script. The film was released in 1968 and received some harsh reactions from the critics, so the company changed the title into Der Kleine Vampir/Little Vampire for the movie's re-release in 1969, and the film finally received some recognition.
