SVU, DAWSON'S STARS LAND NEW GIGS

Stephanie March, who left NBC's Law & Order: SVU in October 2003, when ADA Alexandra Cabot was sent into the Witness Protection Program with a new identity, has joined L&O creator Dick Wolf's latest legal drama, Conviction. Meanwhile, Dawson's Creek alum Kerr Smith has been bumped up to series-regular status on NBC's E-Ring, where he has been guesting as Special Ops team member Bobby Wilkerson.
