Tonight on TV

The big five are pulling out the last of the reruns, saving up the first run episodes for May sweeps it would seem.

CBS is all repeats with “Ghost Whisperer,” “Moonlight,” and “Numb3rs.”

Fox is no better with a repeat of “House” and the canceled “Canterbury’s Law.”

ABC reruns “Desperate Housewives,” then lays in a new “Duel” and “20/20.”

NBC begins with reruns of “Most Outrageous Moments” and then ends with a new “Dateline NBC.”

Over at The CW, it’s “Friday Night Smackdown” all night.

But don’t worry, the cable nets have it going on tonight.

Cable’s got it covered

At 9:00, E! has a new “True Hollywood Story” on Mariska Hargitay and her background is quite fascinating, so that should be a good one. 

Sit down with the kids for SCI FI Channel’s “Sarah Jane Adventures” at 8:00, then stick around for the fourth season premiere of “Doctor Who” with a cameo by Kylie Minogue. That’s followed by “Battlestar Galactica.”

There’s also a new “What Not To Wear” on TLC and “48 Hours on WE,” on WE.
