Twitter's top trending item Wednesday was a promotion for the new slasher flick "Happy Death Day," directed by Christopher B. Landon. It's slated to be released on Oct. 13 by Universal Pictures. The promotion got a poor reaction from users who noted how inappropriate it was amid reports of a deadly fire in a London tower.

Another user, however, pushed back, saying that people complaining about the movie's promotion should "grow up."

The fire in Grenfell Tower in White City began at 1 a.m. local time and engulfed the 24 story building. Police confirmed that six people were confirmed dead, 20 people are in critical care and 74 injured people were taken to the hospital.

That number is expected to significantly rise considering the tower housed as many as 600 people and had 120 different apartments. The flames engulfed over twenty stories of the tower.

More than 250 firemen from all over London descended on the tower in flames, and had difficulty containing the blaze: "In my 29 years of being a firefighter, I have never, ever seen anything of this scale," Dany Cotton, commissioner of the London Fire Brigade, told the New York Times on Wednesday.

Jody Martin, a witness interviewed by the Telegraph on the day of the fire, said that he "watched one person falling out, I watched another woman holding her baby out the window... hearing screams, I was yelling everyone to get down and they were saying 'We can't leave our apartments, the smoke is too bad on the corridors.'"

Additionally, there’s a lot of missing people. A community leader that spoke to The Daily Mail under the condition of anonymity said that he believed that nobody from the top three stories survived and that the tower could collapse within the next 24 hours.

"We have a list of missing people - there are so many. It's possible there are more than 50, possibly hundreds," he said.

The response by British politicians was forceful. Prime Minister Theresa May said she was "deeply saddened" and promised an afternoon meeting to discuss the government’s response. London Mayor Sadiq Khan praised the responders and said that he was going to be asking questions about the conditions surrounding the fire.

"There will be a great many questions over the next couple days as to the cause of this tragedy and I want to assure Londoners that we will get all the answers," Khan said in a statement.
