Jessica Harper, Suspiria

We love made-up holidays around here (especially National Donut Day and Treat Yo Self Day), but our favorite opportunity to celebrate is every Friday the 13th. We just use it as an excuse to watch our favorite horror films and shows and scare ourselves silly. Here are a few we love, all free to watch on Tubi TV:

Suspiria (1977)

With its full use of the Technicolor palette, Dario Argento’s film is as pretty as a painting, but don’t let those bright colors fool you: this movie is dark. Its opening scene is infamous for its brutality, but if you can make it past that, you’ll experience a film that IGN named one of the best horror movies of all time

Watch–or rewatch–Argento’s giallo masterpiece before the remake starring Tilda Swinton, Dakota Johnson, and Chloe Grace Moretz arrives in 2017 to give you nightmares.

Paranormal Activity (2009)

This truly terrifying found footage film launched a number of sequels (also available on Tubi TV), but the original still haunts us. Years have passed and we’ve seen inferior films in the same style, but don’t let that color the original’s impact in your mind. “Paranormal Activity” uses its small budget and tiny cast to their full potential, creating a chilling movie that deserves to have inspired imitators.

The series is theoretically over, but we still have so many questions about this huge franchise.

Invasion of the Body Snatchers (1978)

Horror remakes often get a bad rap, but this one is just as good as the 1956 original. Other than providing one of our favorite gifs, this movie is genuinely creepy and features great performances from Donald Sutherland, Jeff Goldblum, Veronica Cartright, and Leonard Nimoy.

See it so you can nod with awareness when someone mentions “pod people” and say, “I understood that reference.”

Masters of Horror (2005-2007)

When two hours of scares just isn’t enough, there’s this Showtime anthology series to binge for a whole night of terror. The series kicks off with an episode from the team behind cult favorite Bubba Ho-Tep, and then has big names behind the camera like Argento, Tobe Hooper, Mick Garris, Joe Dante, and John Carpenter.

You won’t sleep, and that’s not just because there are two full seasons of episodes to watch.
