“The Karate Kid” is returning the theaters for one night in April, ahead of the release of the sequel series “Cobra Kai”, set to debut on YouTube Red in May.

Those turning out to see the classic 1984 movie on Wednesday, April 25 will also get to see the first two episodes of “Cobra Kai,” which follows up on hero Daniel LaRusso and villain Johnny Lawrence 34 years after their face-off at the climatic All Valley Karate Tournament.

Actors Ralph Macchio and William Zabka are reprising the characters, respectively.

Nearly 700 theaters nationwide are participating in the Fathom Events screening. In the Pittsburgh area, four Cinemark theaters will have showings, starting at 7 p.m.

The original film featured the late Pat Morita as Mr. Miyagi, a karate master working as a maintenance man who teaches Daniel karate to defend himself from the bullies tormenting him, using methods that at first seem like chores . It culminates in the tournament, where Daniel defeats Johnny .

In “Cobra Kai,” Daniel has a family and is running a successful chain of car dealerships. Johnny’s life hasn’t been as good, and he seeks redemption by reopening the Cobra Kai karate dojo.

While Mr. Miyagi taught Daniel that karate was for defense only, Johnny’s teacher at Cobra Kai was harsher, teaching his students to strike first, to strike hard and to be without mercy .

“Cobra Kai” will debut April 24 at the Tribeca Film Festival, and will launch onYouTube Red , a paid service, on May 2.
