Cops are investigating a double shooting — including one fatality — in the now-famous L.A. neighborhood where the movie “Friday” was filmed.

According to the L.A. County Sheriff’s Department … homicide detectives responded to a shooting call around 11:30 AM on April 20 in South L.A., near 126th and Normandie … it’s the same block where Ice Cube’s character lived in the movie.

Cops tell us a man was pronounced dead at the scene, and a woman was transported to a local hospital and treated for her injuries. Law enforcement sources tell us they were hit in a drive by shooting.

For those not familiar with the area … this is where Cube’s “Friday” character, Craig Jones, chilled and smoked weed with Chris Tucker’s character, Smokey. They actually filmed the movie here, not on a studio backlot.

Our law enforcement sources tell us the victims were in the area to check out the house … remember this happened on 420 and “Friday” is a big deal in marijuana culture.

It’s interesting … we’re told some folks in the neighborhood are fed up with the daily traffic as their block’s become a tourist attraction.

The Sheriff’s Department is still searching for suspects, and is asking anyone with information about the incident to contact its Homicide Bureau.
