Picha's next film was the 1980 film "The Missing Link". Though it wasn't as successful as "Tarzoon", the film was entered into the 1980 Cannes Film Festival. Picha also adapted the film into a comic strip. In 1984, the film was released into the U.S. under the title "B.C. Rock". Major changes to the film included newly written dialogue by the comedy duo The Funny Boys (Jim Vallely and Jonathan Schmock), recut footage, different voices, different instrumental score, the absence of the narrator (with the main character telling the story), and nearly all the songs written and performed by Leo Sayer have been replaced by songs by other artists (including Steel Breeze, Hall &amp; Oates, and Rick Wakeman) in order to attract a wider audience. Unfortunately, the film was poorly promoted on video and faded into obscurity. However, this version manages to have a cult following to this day. Picha's future work would never be released in American theaters or any home video format.
