Former Walking Dead showrunner to develop The Omen TV series. From SCREENRANT

Though Glen Mazzara (The Shield) hasn’t predominantly worked within the horror genre, he does have some experience: he took over as showrunner of AMC’s The Walking Dead from creator Frank Darabout in the middle of the zombie drama’s second season and led the series to then-record ratings. Mazzara executive produced the series until the end of season 3 when he split from the show

Now Mazzara is returning to Fox Television Studios – where he worked on The Shield – to pen a television series based on the 1976 horror film The Omen, titled Damien.

According to THR, Mazzara will write the script for Damien, which will air on Lifetime. The Omen, written by David Seltzer (My Giant) and directed by Richard Donner (Lethal Weapon), followed a couple – played by Gregory Peck and Lee Remick – whose son died during birth, prompting them to adopt an orphan. Later, they learned that the child, Damien, was the Antichrist. The Omen has since spawned two theatrical sequels, two TV movie continuations, a 2005 miniseries adaptation, and a 2006 remake, most of which were written by Seltzer.

Though there have been some less-than-successful sequels and adaptations of The Omen, Mazzara has experience in bringing movies to the silver screen. In 2008, Mazzara created a TV series for Starz based on the Oscar-winning film Crash

And of course, this isn’t the first time we’ve seen an old scary movie turned into a TV show. Of late, there’s been the Psycho prequel Bates Motel, the Silence of the Lambs prequel Hannibal, and a miniseries adaptation of Rosemary’s Baby, the first two of which have been rather successful.
Damien will be Mazzara’s first return to television since his stint on The Walking Dead, but given his experience with horror and adapting movies for television he seems to be well prepared for the job. What’s most interesting about Damien is the network on which it will be airing since Lifetime is known for creating typically female-geared dramas.
However, Lifetime is testing the waters in genre TV with Witches of East End – season 2 will debut in July – and upcoming dystopian drama, The Lottery. The network has also seen success with its dark family-centric TV movies such as Lizzie Borden Took an Ax and The Flowers in the Attic, the latter of which is getting a sequel – Petals in the Wind. Alongside these darker supernatural dramas, perhaps Damien won’t feel so out of place.
