'Cavegirl' clan adds Zachar, Momsen

Danny Peacock will direct film based on BBC series

More Berlinale coverage

BERLIN -- Taylor Momsen of TV's "Gossip Girl" and Jacob Zachar of ABC Family's "Greek" are in talks to join Thora Birch in the cast of "Cavegirl," a big-screen version of the 1980s BBC series.

The U.K. Film Council backed the development of the project, which is being repped for international sales here by U.K. finance, production and sales banner Carnaby International.

Written by Danny Peacock, who wrote and directed two seasons of the original show, "Cavegirl" will mark his big-screen directorial debut.

The $6 million-budgeted movie is set to go before cameras in South Africa in April and is being produced by Andy Bell and Tim Woolford in association with the country's Cosmic Films. South African producer Costa John Theo takes executive producer credits on the project.

The action comedy is billed as being a film about teenage problems in a stone age world. The filmmakers are in negotiations with Robin and Barry Gibb to write the music, Carnaby International head of sales Ian Hall said.

Carnaby also has sealed a deal with Sony for the U.K. rights to Jake West's comedy horror "Doghouse," starring Danny Dyer, Stephen Graham and Noel Clarke. Currently in postproduction, the movie centers on a group of men who head to a remote village to help one of their friends get over his divorce. When they get there, they discover that all the women have been infected with a virus that makes them man-hating cannibals.

And Carnaby is in final negotiations with German star Franka Potente to take the lead in its action thriller "The Long Weekend," from writer-director Julian Gilbey. Currently budgeted at about $4 million, Gilbey's script details the story of a group of average joe rock climbers who stumble on a kidnap victim being held hostage underground. They help her escape and are then chased by the kidnappers as well as killers hired by her father to kill the kidnap perps.
