While "Terra Nova's" Jim Shannon blew up Hope Plaza before returning to the prehistoric past, his portrayer, Jason O’Mara is taking a slight detour to the 1960s.
Deadline is reporting that O'Mara has been cast in the untitled drama pilot that is based on the real life story of Ralph Lamb, a former rodeo cowboy turned Sheriff of Las Vegas during the '60s. Veteran film actor Dennis Quaid will play Ralph Lamb, while O'Mara will be Ralph's younger brother, Frank.
"The Shield" star, Michael Chiklis is also on board the project as Johnny Savino, a Chicago mob fixer who is bent on transforming Las Vegas to suit his own purposes as he comes into conflict with Sheriff Lamb. Carrie-Anne Moss has also signed on to play the female lead, A.D.A. Katherine O’Connell, with Michael Reilly Burke as her boss, D.A. Reynolds; Michael O’Neill as Las Vegas Mayor Bennett and James Russo as Big Tuna, a longtime gangster who runs Vegas for the Chicago mob.
Because there is still a chance that talks between 20th Century Fox TV and Netflix may produce a second season of "Terra Nova," O'Mara is only in "second position" on the Ralph Lamb project. That means if "Terra Nova" is revived, O'Mara will return to that series and his part in the Lamb pilot will either be dropped in the potential series or recast.
The untitled Ralph Lamb pilot will be directed by James Mangold from a script by "Goodfellas" writer, Nicholas Pileggi and Greg Walker. It is expected to begin production soon.
