Hulk/Rocket dynamic

According to Mark Ruffalo, one of the highlights of "Infinity War" will be the newly formed friendship between the Hulk and Rocket Raccoon, and their dynamic will bring the fun and excitement in the film's battle sequences.

"Its a very funny relationship that the two of them have: First of all, the biggest superhero and the smallest," Ruffalo said. "Just keeping them in a frame together is a feat and hilarious in itself."

The Avengers will join forces with the Guardians of the Galaxy to stop the Mad Titan and his forces from invading Earth and collecting the Mind and Time Stones. The leaked "Infinity War" teaser revealed the team-up of Iron Man, Star-Lord, and Doctor Stephen Strange.

Rocket is always seen with Groot in the comics and films, but it looks like the latter will be forced to work with other Marvel heroes to fight Thanos. Movie stunt actor Terry Notary teased that Teenage Groot will have a new role model [VIDEO] in the movie, and comic book fans theorized that it could be Thor, Hulk, or Spider-Man.

'Avengers 3' a heist movie?

Movie directors Joe and Anthony Russo stated that "Avengers: Infinity War" will be a "heist-styled" film as they told CNET that the biggest factors in the sequel are Thanos and the Infinity Stones. The directors explained that Thanos's mission to get every stone in the Marvel Cinematic Universe led to them create a narrative based on heist movies, bringing with it the suspense, excitement, and the thrill of the film.

The heist elements in the sequel should provide a different sense of energy than other MCU movies. The focus on Thanos as a villain with a heist angle should be a great combination, considering that most heist movies have the good guys planning and organizing the theft, but this time the audiences are rooting for the villain.

Cast member Robert Downey Jr. posted an Instagram photo teasing the surviving heroes in "Infinity War, and these are Iron Man, Captain America, Black Widow, and Ant-Man. Marvel Studios President Kein Feige told Fandango that a female version of Thor would be introduced in phase 4, possibly teasing the death of original God of Thunder.
