John Clisham, a longtime employee of James Cameron that most recently worked on the 3D conversion of Titanic, will write and direct the Untitled John Clisham Dinosaur Thriller for Warner Bros.

This giant monster movie follows a pack of rapidly mutating dinosaurs that stomp all over modern day Los Angeles. Mike Bayman is co-writing the script, the contents of which are being kept mostly under wraps.

The project was originally conceived as a large-scale webseries. Warner Bros. moved on the property after seeing some impressive early test footage, and acquired it as a feature film.

There is no news on when the film will actually go into production.
