The fourth movie in the “Predator” franchise hits theaters today, which means it’s time to (re)watch all of the previous installments. There are three films in the main series, as well as two crossover flicks with the “Alien” franchise, to check out before going to see “The Predator.”

Shane Black, who played Hawkins in the first movie, directed and co-wrote this new sequel that follows a crew of ex-soldiers that must save the human race when a group of Predators arrives. Boyd Holbrook (Quinn), Trevante Rhodes (Nebraska), Jacob Tremblay (Rory), Keegan-Michael Key (Coyle), Olivia Munn (Casey), Thomas Jane (Baxley), Alfie Allen (Lynch) and Sterling K. Brown (Traeger) star in the movie.

Before you get to that, though, here’s where you can watch all of the main and crossover “Predator” movies online.

Main Movies

“Predator” (1987)

Arnold Schwarzenegger (Dutch) and Carl Weathers (Dillon) starred in the first movie in the series, which saw soldiers being hunted by a Predator in a Central American jungle. The John McTiernan-directed flick is available to rent or purchase, starting from $2.99, on Amazon Prime, YouTube, Google Play, Vudu, iTunes and HBO Now.

“Predator 2” (1990)

This first sequel featured Danny Glover’s Lieutenant Mike Harrigan trying to stop Kevin Peter Hall’s The Predator from getting his Los Angeles prey. Stephen Hopkins was the director this time around, and fans can see his work by streaming the movie at all of the same locations as “Predator.”

“Predators” (2010)

The ever-changing cast, this time around, included Adrien Brody (Royce), Topher Grace (Edwin), Alice Braga (Isabelle), Walton Goggins (Stans) and Laurence Fishburne (Noland).
