This is a spin off of "The Practice", so I figure C&J is probably the best place.
Boston Legal, home of former Trek actors.
NANJAO's on John Laroquette:
This is the second time he's starred as a lawyer. Of course, in this case, he's the anti-Dan Fielding. He's the one trying to maintain a sense of respectability in the face of a staff full of sexual shenannigans.
And of course, the scenes between him and Alison La Placa are rather fun, in view of the old "John Laroquette Show", wherein their characters also had a relationship.
also 7 of 9 in a Boston legal episode ,Spring fever! She's a lot better than Kes! (sorry kes Fans).
the 4 were a Trek at one time or another!
Yes, Jeri Ryan (learn actors's names, will you?) did guest on Boston Legal.
Jeri Ryan, William Shatner, Rene Auberjonis and John Larraqutte.
Happy?
You forgot about Scott Bacula (Capt. Archer) on Boston Legal.
I knew I'd forgotten someone 
P.S. CCabe, how's your evil twin?
no, that's Cpt. J. Archer!
--------------------------
I just choose the charecters' names that they were most well know as.
This is the second time he's starred as a lawyer.
At least the third, maybe. If you count his appearance as a lawyer who causes trouble for Bruce Willis' character Walter, then defends him, in the 1987 comic romp Blind Date.
I'd forgotten about that. I meant in a series.
