HOLLYWOOD (CBSLA) — Marvel fans were in the endgame Thursday as they watched the three-hour epic finale of 10 years and 22 films of superheroes who have conquered the global box office.

It’s been an emotional three days for 500 “Marvel Avengers: Endgame” fans as they sat through the final movie of the 22 movie series.

“I cried like five times,” said one moviegoer.

“It was amazing. I just peed after waiting 2.5 hours. That’s why I’m out of here first,” said another moviegoer.

They’ve slept inside El Capitan for three days for the Marvel Marathon starting with the first movie and ending with the three-hour movie.

“My seat. My house. My bed. My bathroom. My everything has been here in El Capitan,” said an Avengers fan.

“Avengers: Endgame” opens tonight, shattering presale records after last year’s “Infinity War” left moviegoers stunned and impatient to see how Earth’s mightiest heroes bring the galaxy back from the snap heard ’round the galaxy.

“It’s amazing,” fan Kevin Calba said. “Especially how this is the last, final movie. For 10 years, we’ve been waiting for it. It’s going to be amazing.”

Dedicated fans like Kevin Calba have taken their commitment to see “Endgame” to the next level by watching three days of back-to-back Marvel movies at the El Capitan Theatre, one of 12 theaters to hold the marathon event. After starting with “Iron Man” and going through all the Thor, Captain America and previous Avengers films, these moviegoers will be the first to watch “Endgame” at the El Capitan.

“Everybody here is here for the same reason – we want to have a fun experience, and we want to see ‘Endgame’ the way that it’s kind of meant to be seen,” fan Chris Colman said.

During the film fest, food trucks have come to help vary the menu, and there have been raffles and games between films. Fans have also been spotted taking exercise and nap breaks on the floor of the theater.

“Being able to see them all at once like this, surrounded with like-minded nerds, it’s amazing,” fan Maria Keller said. “The energy is great.”

And speaking of breaks – there has been much discussion about the three-hour run time for “Endgame.” But fans who have already seen the film, without divulging any spoilers, say that there are a few reliable spots where a bathroom break can be taken without missing too much action – at the point of the San Francisco and New Jersey title cards, while the Hulk is having lunch, and while Tony Stark and Pepper Potts are talking.
