The countdown to ABC's "Thank Goodness It's Thursday" is officially on! A new promo that featured the entire casts of "Grey's Anatomy," "Scandal" and "How to Get Away with Murder" was released earlier today for the three Shonda Rhimes-produced shows, according to TV Line.

The promo features the actors and actresses of the three TGIT shows as they played around with popcorn and more importantly, wine! The casts of the three shows looked like they were having a great time as they danced around with their co-stars to a fun, upbeat song.

The promo started with the three lead actresses, Ellen Pompeo, Kerry Washington and Viola Davis, as they poured some hefty glasses of red wine. The trailer also gave fans a first look at some new full-time cast members, which included Portia De Rossi and Cornelius Smith Jr., who were both added as "Scandal" series regulars, reported E! News.

Rhimes' TGIT returns on Thursday, Sept. 24 starting with "Grey's Anatomy" at 8 p.m., followed by "Scandal" at 9 and "How to Get Away With Murder" at 10 p.m., according to ABC.
