"Avengers: Age of Ultron's" trailer will be aired in next week's episode of "Agents of SHIELD," as its teaser is been tied with 28 October episode "A Fractured Horse."

The announcement of the trailer release with "Agents of SHIELD" was made by Robert Downey Jr. who confirmed that he would feature in "Captain America 3."

Marvel tweeted the news with the picture of Avengers. 

Meanwhile, the first footage of the Avengers sequel was shown at San Diego Comic Con in July. Downey Jr. and other cast members introduced the trailer to the 7,000 fans. It showed the actors lounging in Tony Stark's home as everyone tries to lift Thor's hammer. Stark tries but fails. All avengers fail to lift hammer except Captain America.

"Avengers: Age of Ultron" might see Stark devising a peace keeping programme and things could go haywire when Ultron turns evil. Hulk, Captain America, Thor and others might go on a mission to save the planet from Ultron.

The storyline of the film is said to be gripping and is believed to be one of the main reasons why fans are waiting for it release with much anticipation. With more than 3000 VFX effects, the film is one of the highest to use it in any Marvel movie till date, according to the report.

"Captain America: The Winter Soldier," had about 2,500 VFX effects and "Guardians on the Galaxy," had 2,750. Marvel executive producer Victoria Alonso said that they have roped in VFX experts from all over the world and this would add a lot to the "Avengers: Age of Ultron's" visual aspect, according to Hollywood Reporter.

She also said that Marvel's process is "ever evolving with collaboration, starting with story and visual development." The story "starts with the comics and then ideas for how to make it better for the film medium."

"Avengers: Age of Ultron" is slated to release next year. The cast of the film includes Chris Hemsworth as Thor, Robert Downey Jr As Iron Man, Mark Ruffalo as The Hulk, Jeremy Renner as Hawkeye, Scarlett Johansson as Black Widow, Chris Evans as Captain America, Elizabeth Olsen as Scarlet Witch, and Aaron Taylor-Johnson as Quicksilver.
