I'm not sure if I read your question at the end there correctly Michael but if you're asking if 'that girl' is Billie Piper then I can reply in the affirmative. Here's a recent quote from the media press:
"Riding crops, high heels, stockings and suspenders? Billie Piper's newest role as a prostitute in Secret Diary Of A Call Girl is a far cry from her role as Dr. Who's assistant where the one-eyed monsters were a different species altogether!"
As to favourite TV shows, I too am living more in the past than the present. If we take all the Star Trek's (sans Deep Space 9) and Doctor Who as givens, here's a sampling of my taste:
"Buffy the Vampire Slayer" was probably the best serial drama of the decade {and no it wasn't just that I fancied SMG ... I'm more of a Charisma Carpenter guy :lol:}.
"Firefly" was and may well be again (fingers crossed) wonderful
"Space Above and Beyond" never got the chance it deserved
"Dark Angel" was just starting to get into the deeper and wider story lines when the money men stepped in
"Battlestar Galactica" old and new (tho' as a note to the writers of the new, can we
please have some characters to admire and like - humans have good natures too you know!)
"Babylon 5" the most glorious Sci-Fi ever made?
"CSI" (the original is by far the best)
"Law & Order" (again the original is best)
"Frasier" was consistently good for it's long run
"Stargate" was a rival for "Babylon 5" for the brightest sun in the Sci-Fi firmament
"Space 1999" looks horridly dated now but it was the bees knees when I was a kid (and I
still want a real Eagle

)
"Alias" was seting out to be marvellous and then the bean counters had the writers dumb it down for the hard of thinking

.
There're more but that's a good sample of the inside of my head :lol:.
