"Avengers: Age of Ultron" is set to release almost a year later on May 1, 2015. For those eager fans, here are few things that we know so far about the "Avengers" franchise's second instalment. The year will see the release of two more superhero films including "Fantastic Four" and "Ant-Man."

"Avengers 2" Cast: Fans should brace themselves for a power-packed instalment wherein almost all the "Avengers" cast will make a return. The film features Robert Downey Jr. as Tony Stark/Iron Man, Chris Hemsworth as Thor, Mark Ruffalo as Dr. Bruce Banner / The Hulk, Chris Evans as Steve Rogers / Captain America, Scarlett Johansson as Natasha Romanoff / Black Widow and Jeremy Renner as Clint Barton / Hawkeye.

In addition, S.H.I.E.L.D.'s former director Nicky Fury (Samuel L. Jackson) and James Rhodes/ War Machine (Don Cheadle) will also be joining the team.

New Superheroes: Wanda Maximoff/ Scarlet Witch (Elizabeth Olsen) and her twin brother Quicksilver (Aaron-Taylor Johnson) will be introduced to the movie adaptation of Marvel's universe.

Scarlet Witch has ultimate telekinetic abilities and can manipulate spells. Meanwhile, Quicksilver has the power to move at superhuman speed.

Josh Brolin, Hayley Atwell, Cobie Smulders and Thomas Kretschmann will also return as Thanos, Peggy Carter, Maria Hill and Baron Wolfgang von Strucker.

Supervillain Ultron: Fans know that Ultron portrayed by James Spader is the ultimate villain that Marvel heroes must defeat to save the world. Ultron is a super intelligent robot who was created by Ant-man, but he is enraged with hatred towards his creators and wishes to rule the world. He is one of the most powerful and darkest villains of Marvel Universe. His powers include superhuman levels of stamina, speed and strength. He is indestructible and can transform into humanoids. According to Whedon, the film avatar of Ultron will be different from the original created by Ant-Man. Director Joss Whedon earlier told that they are creating their own version of Ultron's origin story which will "come directly from The Avengers we already know about" (via slashfilm.com)

More Villains: Another villain to watch out for is Thomas Krestschmann's Baron Wolfgang von Strucker. Not much has been revealed about the character, but according to the original "Avengers" storyline he is one of the most powerful leaders of HYDRA and former Nazi officer.

Plot Details and Opening Shot: Production of the movie is halfway done even then official synopsis remains to be revealed. Recently plot details revealing first few minutes of the movie surfaced. According to Latino Review the opening scene is going to be a full-on action sequence. Fans must also note that events of "Captain America: The Winter Soldier" will have an impact in the storyline of "Avengers: Age of Ultron." "Captain America 2" will set the stage for "Avengers 2" in a way. According to the recent reveal, the first 20 minutes of "Avengers 2" will showcase the events that take place immediately after Baron von Strucker post-credit scene in "Captain America 2." The opening shot sees Avengers busting into Baron Stucker's HYDRA outpost. However, he has his own army to defend himself. He has Loki's personnel and the Chitauri weaponry and Quicksilver and Scarlet Witch to fight back. Scarlet uses her abilities and cast a spell on Hulk who starts to think that Leviathan is still alive. But avengers successfully defeat the trio and celebrate the victory at Avengers Tower.

The superheroes also take turns to pick Thor's hammer but fail to do so.

Hulk has 'Bigger' and more 'Complex' role: In an interview with Total Film, Mark Ruffalo revealed that his character is "bigger than last time, and it's more complex and it has more layers and a bit more arc." It is assumed that he was talking about the burgeoning romance with Black Widow as hinted by spoilers from the opening shot. Two of them allegedly find a romantic connection with each other.

Jane and Thor's Split: Not all is good between Jane and Thor in "Avengers 2." It is said the alleged opening scene of "Avengers: Age of Ultron" sees the Asgardian god at the bar looking at Jane (Natalie Portman) with Richard (Chris O'Dowd's character from "Thor: The Dark World).
