ABC has announced premiere dates for its Captain America TV series spin-off Marvel’s Agent Carter and new musical dramedy Galavant.

Both will premiere the first week of the new year, with Galavant hitting on Sunday, Jan. 4 at 8 p.m. and Agent Carter arriving on Tuesday, Jan. 6 at 9 p.m. The dramas will fill the Once Upon a Time and Marvel’s Agents of SHIELD spots, respectively.

The hiatus-filling scheduling is designed so that ABC will run fewer repeats during the season and more original epiosdes. Once Upon will return March 1 and SHIELD will return on March 3. Here’s the trailer for Galavant and teaser for Agent Carter, plus full official descriptions of both shows below.

Galavant – Screenwriter/executive producer Dan Fogelman (Crazy, Stupid, Love) unites with Broadway and Hollywood award-winning musical team—composer Alan Menken (The Little Mermaid) and lyricist Glenn Slater (Tangled). Once upon a time, the dashing hero, Galavant (Joshua Sasse), lost the love of his life, Madalena (Mallory Jansen), to the evil King Richard (Timothy Omundson). Now, our fallen hero is ready to take revenge and restore his “happily ever after.” But it won’t be without a few twists and turns along the way.

Marvel’s Agent Carter – It’s 1946 and peace has dealt Agent Peggy Carter (Hayley Atwell), a serious blow as she finds herself marginalized when the men return home from fighting abroad. Working for the covert SSR (Strategic Scientific Reserve), Peggy finds herself stuck doing administrative work when she would rather be back out in the field, putting her vast skills into play and taking down the bad guys. But she is also trying to navigate life as a single woman in America, in the wake of losing the love of her life, Steve Rogers – aka Captain America. When old acquaintance Howard Stark (Dominic Cooper, Marvel’s Captain America: The First Avenger) finds himself being framed for unleashing his deadliest weapons to anyone willing to pony up the cash, he contacts Peggy — the only person he can trust — to track down those responsible, dispose of the weapons and clear his name. He empowers his butler, Edwin Jarvis (James D’Arcy), to be at her beck and call when needed to help assist her as she investigates and tracks down those responsible for releasing these weapons of mass destruction. If caught going on these secret missions for Stark, Peggy could be targeted as a traitor and spend the rest of her days in prison – or worse.
