'Yes' in answer to your question. They've adapted the Terminator movies into a TV series called The Sarah Connor Chronicles. Well not quite adapted, a TV series has been made to fill in the blanks between 'Terminator 2: Judgement Day' and 'Terminator 3: Rise Of The Machines'.
Its an ambitious project to take on especially since the Terminator series is so well known.
The pilot episode is available here for the moment (don't worry - it hasn't got Spanish subtitles as the site mentions), on the excellent Stage6 site. Go check it out!
From what I've seen, the plot follows a similar formula to the films. A bad terminator is sent back in time to destroy John Connor (the savior of humanity) whilst a good terminator is sent back by the human resistance (in the future) to counteract the bad one and keep John alive.
There's no real famous faces in this as far as I can see except Summer Glau from the excellent (yet canceled!) series 'Firefly' (which later got made into a film called 'Serenity'). Also the terminators are lacking that Stan Winston touch in regards to the visuals although I doubt the studio would want to spend too much on makeup/animatronics/CGI for a TV show.
According to IMDb the series should start (in the US) in the early part of next year but I'm kinda expecting it not to get that far. It looks like a good show but it also looks like it will flop (not sure how to explain that though). Virgin Media have apparently secured the rights to show this on demand in the UK so I'll look out for it in the future.
