Universal Pictures has debuted the first trailer preview for Happy Death Day, originally entitled Half to Death, which reveals the first of many deaths for a young college student named Tree Gelbman (Jessica Rothe). Blumhouse produces this original and inventive rewinding thriller where Tree relives the day of her murder with both its unexceptional details and terrifying end until she discovers her killer's identity. This 20-second video will get fans ready for the first full trailer that arrives on Wednesday.

Universal Pictures debuted this trailer preview on its YouTube page, which is where the full trailer will arrive on Wednesday. The trailer preview begins with Tree Gelbman waking up in a dorm room, before returning to her sorority house to get ready for her own birthday party. While the party is in full swing, Tree is seen entering a darkened room, where she is met by a masked intruder, who breaks a bong tube and uses it to kill this young woman. Who this killer is and why the crazy baby-faced killer is targeting Tree Gelbman is unclear as of now, but hopefully we'll get more clues when the first full trailer arrives.

The supporting cast includes Israel Broussard, Ruby Modine, Rachel Matthews, Charles Aitken, Jason Bayle, Phi Vu, Donna Duplantier, GiGi Erneta, Tenea Intriago, Rob Mello and Cariella Smith. Happy Death Day is directed by Christopher Landon and written by Landon and Scott Lobdell. Christopher Landon made his directorial debut with Paranormal Activity: The Marked Ones in 2014, which he followed up with 2015's Scouts Guide to the Zombie Apocalypse. He has also written the screenplays for movies such as Blood and Chocolate, Disturbia, Burning Palms, Paranormal Activity 2, Paranormal Activity 3 and Paranormal Activity 4.
