The triumverate of pay cable networks --- HBO, Showtime, and Starz --- all took heed of the old adage, "You ain't nothing if you don't bring footage to Comic-Con."  So today we have trailers for each network's respective flagship drama: season five of Dexter on Showtime, the second half of season three of True Blood on HBO, and the Spartacus: Blood and Sand prequel miniseries Spartacus: Gods of the Arena.  Check out all three after the jump.

I am currently watching True Blood, and will certainly reunite with Dexter come September.  But I think this trailer has inspired me to catch up with Spartacus: Blood and Sand in time for the prequel.

Spartacus: Gods of the Arena

Spartacus: Gods of the Arena comes to Starz in January 2011.  Here's the official synopsis:

Spartacus: Gods of the Arena focuses on the House of Batiatus, in the days before Spartacus arrived. Hannah's Batiatus is not yet the head of the family, or the ludus. Gannicus is the undisputed lead gladiator in the Ludus, but in the class-conscious world of ancient Capua, the House of Batiatus still hasn't earned the respect of local society, or the right for its gladiators to fight in the championship bouts. Gannicus must survive the arena to not only keep his place in the ludus but also rise to become the champion in all of Capua.
