Avengers Fans Upset With 'Endgame' Spoilers on Social Media

No spoilers, please!

Avengers fans are begging people on social media not to ruin "Endgame" before they can see it. But some people can't help but ignore the message — including one NFL player.

Buffalo Bills running back LeSean McCoy tweeted about the movie's emotional ending moments after seeing the superhero film over the weekend. He questioned a certain's character's fate in the 11th hour.

Moviegoers were upset. Some even started a petition to have McCoy fired for spoiling the magic.

The final installment in the Avengers franchise is so action-packed, and filled with endless twists and turns, that even the movie's stars pleaded with fans to protect the film's secrets.

It's even spread to classrooms. One teacher posted a notice on his door warning his students not to talk about the movie until he removes the sign. And one teen was so upset when a classmate revealed the dramatic ending that he punched the boy right in front of the teacher.

"Avengers: Endgame" is getting rave reviews for its conclusion of more than 10 years of films. It had the biggest opening weekend of all time, beating out its predecessor, "Avengers: Infinity War."
