BERLIN — Helmer Sebastian Niemann and producer Christian Becker of Munich-based Rat Pack are prepping a follow up to “Hui Buh — Das Schlossgespenst” (Hui Buh — The Goofy Ghost), one of this year’s most successful German films.

Tyke pic, which starred the voice and CGI likeness of comedy star Michael Herbig (“Spaceship Surprise — Period 1″), grossed Euros 10.4 million ($13.8 million) at the box office.

Herbig is expected to return for the sequel, tentatively titled “Hui Buh und der verbotene Palast” (Hui Buh and the Forbidden Palace), in which Hui Buh travels to the Far East.
