LOS ANGELES -
In the decade that "Touched by an Angel" executive producer Martha Williamson has been away from series TV, much has changed. A new golden age has brought more daring shows, from "Mad Men" to "House of Cards" to "Breaking Bad," and more ways to see them.
But Williamson says her Hallmark Channel series, "Signed, Sealed, Delivered," will be just as comfortable a fit for viewers as "Angel" was during its 1994-2003 run.
"Signed, Sealed, Delivered," debuting 8 p.m. EDT Sunday, stars Eric Mabius ("Ugly Betty") as Oliver, the straight-laced, good-natured supervisor of an offbeat group of U.S. Postal Service employees who become sleuths to get mail to its proper place.
While mail carriers refuse to surrender to the weather, Oliver's crew is undeterred by a missing name or indecipherable address. In the first episode, a boy's urgent letter to an anonymous Grandmom leads them into unexpected territory.
Kristin Booth, Crystal Lowe and Geoff Gustafson co-star as the unlikely Sherlocks. Valerie Harper is a visiting manager in the first two episodes, with Valerie Bertinelli, Marilu Henner and former "Angel" star Della Reese also set to guest star.
There's gentle humor as well, which Williamson traces back to her TV roots writing for variety shows and sitcoms including "The Facts of Life."
On the flip side, Williamson said she hopes her new series will grow to encompass more complex and sensitive issues, such as "Touched by an Angel" did with domestic violence, human rights violations and more. Episode two of "Signed, Sealed, Delivered" about a PTSD-afflicted veteran, heads in that direction.
No matter the topic, the Hallmark Channel series will remain a "safe place" for families who still want and deserve less-edgy programming, she said.
