This was a potential series for NBC in which David Tennant played Rex who was a Chicago litigator who becomes so crippled by anxiety that he takes to coaching his clients into representing themselves. David has described this as a "comedy drama."
Unfortunately on Sunday 16th May 2010 it was announced that NBC would not be making a full series of Rex Is Not Your Lawyer. Unlike UK television, the US have a policy of announcing that they are making pilots for series. A decision on whether or not it will ever air is made by the network after the pilot is complete.
Shooting of the pilot is believed to have started during the week commencing 23rd November 2009 and finished on Tuesday 22nd December (although David was required all that time).
This is one of the rare clips from the pilot which made it online.
Apologies if the video does not play in your country.
