Syfy dropped trailers for two very promising new shows during NBCUniversal's Upfront presentation on Monday: Nightflyers, a sci-fi horror series based on a novella by A Song of Ice and Fire author George R.R. Martin, and Deadly Class, an comic book adaptation that's executive-produced by Avengers: Infinity War directors the Russo brothers.

Set in 2093, Nightflyers tells the story of a group of maverick scientists and a powerful telepath who set off on an expedition aboard the spaceship Nightflyer in hopes of making contact with a mysterious alien life at the edge of our solar system. As they race toward first contact, terrifying and violent events begin to occur, causing the once tight-knit crew to mistrust each other. It's not long before their main mission becomes survival.

The series stars Boardwalk Empire's Gretchen Mol and The Night Shift's Eoin Macken. It's a co-production between Universal Cable Productions and Netflix, so it will be on Syfy in America and Netflix internationally. It premieres this fall.

Deadly Class is based on a comic series by Rick Remender, who adapted the series for TV with Miles Orion Feldsott. Comedian, comics nerd and Happy! voice actor Patton Oswalt, who introduced the trailer during the presentation, said that it's his favorite comic of all time, which is a pretty good endorsement. Deadly Class tells the story of a homeless teen recruited into a storied elite private school where the world's top crime families send their next generations. Maintaining his moral code while surviving a ruthless curriculum, vicious social cliques and his own adolescent uncertainties soon proves to be vital.

It stars Doctor Strange's Benedict Wong, Teen Wolf's Benjamin Wadsworth and X-Men: Apocalypse's Lana Condor.

It will premiere in 2019.
