'Stranger Things' receives 'graphic violence' warning ahead of Season 4 after Uvalde shooting

In the immediate wake of the deadly school shooting in Uvalde, Texas, Netflix added a warning label to the Season 4 premiere of "Stranger Things."

Netflix added a disclaimer to the Season 3 recap that plays before the first episode of Season 4 ahead of the Friday premiere.

"We shot this season of Stranger Things a year ago," says the card.

"However, given the recent tragic shooting at a Texas high school, viewers may find the first episode's opening scene distressing."

We are deeply saddened by this senseless violence, and our hearts go out to every family grieving the loss of a loved one."

The warning label is only for viewers in the United States.

The premiere episode's description has also been updated to include the warning, "Warning: Contains graphic violence involving children."

Netflix has also added "disturbing images" to the show rating advisories.

Season 4 of "Stranger Things" begins with Mike (Finn Wolfhard), Lucas (Caleb McLaughlin), Dustin (Gaten Matarazzo), Will (Noah Schnapp), and Eleven (Millie Bobbie Brown) as terrifying things begin to happen in Hawkins due to the arrival of a mysterious figure killing local teens.

Following Tuesday's shooting at Robb Elementary School in Texas, which was the deadliest shooting at a U.S. grade school since the 2012 attack at Sandy Hook Elementary School in Newton, Connecticut, "Stranger Things" isn't the only TV show to make changes.

The Season 4 finale of CBS' crime drama "FBI" was cancelled the same day because the finale storyline involved a suspected student's involvement in a deadly robbery. In place of the season finale, the network re-aired the show's 12th episode, "Under Pressure," and it's unclear whether the episode will be re-aired again in the future.
