Turns out the The Starter Wife had a starter ex. When the show returns to USA as a full-fledged TV series, Molly Kagan (Debra Messing) will have a new ex-husband to despise: Peter Jacobson, who played Kenny Kagan in last Summer's miniseries, is now working full-time on House, so his role has been recast, with David Alan Basche taking over as the new Kenny. That got me thinking about other shows that have recast characters mid-series. Want to see the old and new versions of some favorites? Just hit "Start."
