The first American Horror Story: Hotel trailer with the full cast has been revealed, teasing sex, blood and very creepy children.

'American Horror Story: Hotel' Premiere Synopsis Revealed

The trailer showcases all the stars of Hotel in costume as their characters, including Lady Gaga, Sarah Paulson, Angela Bassett and Kathy Bates. It begins with an elevator door opening as John Lowe (Wes Bentley) and his wife Alex Lowe (Chloë Sevigny) walk by.

We are then introduced to the hotel's various zany characters, including drug addict Hypodermic Sally (Paulson), hotel manager Iris (Bates), crossdresser Liz Taylor (Denis O'Hare), actress Ramona Royale (Bassett), tenant Donovan (Matt Bomer), the hotel laundress (Mare Winningham), hotel founder Mr. March (Evan Peters), hotel guests Tristan (Finn Wittrock) and Will Drake (Cheyenne Jackson) and finally, the star of the show, hotel owner Elizabeth (Gaga), a.k.a. The Countess.

Lady Gaga Is 'Bringing Back The Turban' On 'American Horror Story'?

All of these characters either look very sinister or are doing various sinister things as we zoom through the various hallways of the Hotel Cortez. Blond children are seen running throughout. The last shot of Gaga as Elizabeth looks like she is a ghost of some sort.

The song featured in the trailer is "Bury Me" by Brodinski featuring Maluca and Bricc Baby Shitro. The faint sound of the actual American Horror Story theme song is also heard throughout.

The overall feeling of the trailer suggests this will be a very glamorous, stylish season with very dark undertones. You never know who (or what) might be lurking at the other end of the hallway.

American Horror Story: Hotel premieres Wednesday, Oct. 7 at 10 p.m. ET/PT on FX.
