Allentown Prods., headed by documentary filmmaker James Moll, has picked up feature rights to Knott's Berry Farm's Calico Ghost Town and all the rides and original characters created for the theme park and is planning a big screen adaptation.

According to Variety, Allentown director of development Chris W. King shepherded the concept with Moll, who will produce. The story is set in the Wild West at the turn of the century, and centers on the boomtown gold mining town of Calico, which has been overrun by ghosts and evil supernatural creatures.

At its peak, the real Calico had a population of 1,200 and more than 500 silver mines. The Mojave Desert town was abandoned in 1907 and later became a tourist attraction that was at one time owned by Knott's and is now independently operated.

Knott's Berry Farm's version of Calico Ghost Town is the oldest attraction at the amusement park in Buena Park.

"It's the perfect setting for a big, spooky, family adventure with all the elements of a classic Western -- cowboys, showgirls, gunfights, chases through creepy mines -- all with a supernatural twist, " Moll said.

Moll expects to announce additional financing along with a writer and a director later this summer.

No production date has been set.
