Dennis Quaid and Michael Chiklis have boarded a new currently untitled CBS drama pilot based in Las Vegas.

The show would follow the life of rodeo cowboy turned Las Vegas sheriff Ralph Lamb. Dennis Quaid would play the title character in the 1960s-set project. Michael Chiklis would portray Johnny Savino, a Chicago mob fixer whose entrepreneurial ambitions for Vegas collies with Lamb's law-and-order mandate.

James Mangold will be directing the project from a Greg Walker and Nicholas Pileggi script. Cathy Konrad and Arthur M. Sarkissian are produce with the writers and director.

This project is still in development.
