New details and spoilers for "Avengers: Infinity War" will likely reveal the film's Run Time and the status of Captain Marvel's appearance during the story.

'Infinity War's' run time

The movie's co-director, Joe Russo teased the possible run time for "Avengers Infinity" during San Diego Comic-Con last week, as he told Collider that current cut of the film is over two and haft hours, but there was still plenty of work to be done for the final product.

Given the length of the other Marvel Cinematic Universe films like "Avengers" and "Civil War," which are set at two hours and 20 minutes - it is hardly surprising that "Avengers: Infinity War" could only hit a two and haft hour mark.

Russo did admit that there so much more work to be done in the film, but when it is all set and done, the sequel could be one of the best movies in the MCU to date.

Several Marvel fans in SDCC 2017 recorded and leaked the trailer for "Infinity War," which shows the Avengers teaming-up with Doctor Strange and the Guardians of the Galaxy to fight Thanos. Fans were able to see the team-up of Doctor Strange, Iron Man and Star-Lord; Peter Parker donning the Iron Spider suit, which was first seen at the end of "Spider-Man: Homecoming." Steve Rogers returns with a bearded look and possible new name, and Thanos effortlessly cuts through both teams using the Infinity Stones.

No Captain Marvel appearance

Despite a huge cast of characters in the third "Avengers" film, Russo confirmed that Brie Larson's Carol Danvers/Captain Marvel would not be part of "Infinity War." He did not elaborate any further as to why she is not part of the movie. However, Marvel president Kevin Feige and Marvel Studios revealed that the "Captain Marvel" film would be set in the 90's.

It was during Marvel's panel at SDCC 2017 event that the studio revealed a concept art of Carol Danvers fighting the alien forces of the Skrull empire, and a younger Nick Fury will appear in the film. While other fans speculated that the studio might be dodging a possible "Captain Marvel" Easter egg in "Infinity War," it will be interesting to see how the Skrulls will be presented in the MCU.

The Skrulls are a major alien race in the Marvel comics, debuting as the enemy of the Fantastic Four. They are a rival species of the Kree, which were featured in "Guardians of the Galaxy" film and in "Agents of S.H.I.E.L.D." TV series.

Fans are wondering if they are setting the Skrulls for a much bigger role in the MCU, as film versions of the Kree-Skrull War and "Secret Invasion" could be in the cards for Phase 4 soon.

"Avengers: Infinity War" will premiere on May 4, 2018.
