Growing Pains‘ Alan Thicke has been cast in Dan Fogelman’s untitled pilot at NBC. The Grandfathered and Galavant EP also executive produced The Neighbors, which was cancelled by ABC after two seasons.

Per Variety, Fogelman’s untitled project is a dramedy featuring eight people who share the same birthday. Thicke joins a cast that includes: Mandy Moore, Milo Ventimiglia, Justin Hartley, Sterling Brown, Chrissy Metz, Susan Kelechi Watson, and Ron Cephas Jones. Update: 5/13/2016: NBC ordered the show to series with the title, This Is Us.

Thicke tweeted a picture of himself and Justin Hartley, who is currently a series regular on The Young and the Restless. In the tweet, Thicke tagged “@FOXTV” by mistake. The project is being produced by 20 Century Fox for NBC.

Here is what we know about the series so far, from Variety:

[Ventimiglia] will play Jack, who’s described as easy-going and happily married to Rebecca, played by Moore. The couple just moved into their new home in Pittsburg and is on the verge of welcoming triplets.

Hartley, best known from his heavily recurring arc on “Revenge,” has been cast in the pilot as Kevin, a handsome and successful television actor with an underlining boredom in his ultimate bachelor life.

Brown (“Army Wives”) will play Randall, a sharply dressed corporate businessman and family man, based in New York, who’s raising his two young daughters with his wife Beth (yet to be cast). Jones (“Mr. Robot”) will play Randall’s (Brown) biological father who abandoned him at a fire station soon after he was born.

Ventimiglia has been pretty busy as of late. He has just joined the cast of the Gilmore Girls  revival on Netflix. He is also launching a new drama, Relationship Status, for Verizon Wireless go90.
