Just when you think Marvel is upping the ante with its latest traveling attraction, "The Marvel Experience," it makes an even bigger visual splash for the big screen, which is sure to pay off at the box office.

"Avengers: Age of Ultron" is going to have "the most visual effects (VFX) of any Marvel movie to date," said Victoria Alonso, the studio's executive vice president of visual effects and postproduction, according to The Hollywood Reporter.

While addressing an audience filled with Hollywood influencers, Alonso, who is also executive producing the Joss Whedon-helmed flick and Peyton Reed's "Ant-Man," made the announcement during her keynote at the Visual Effects Society Production Summit at the W Hollywood on Oct. 18.

"Alonso also discussed the 'Marvel process,' which she described as 'ever flowing' 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,'" she said.

The level of work is going to heighten. Alonso "anticipates topping 3,000 VFX shots for the Avengers sequel, which would make it Marvel's largest VFX shot count to date. She previously exec produced 'Captain America: The Winter Soldier,' which maxed out at 2,500, and 'Guardians on the Galaxy,' which reached 2,750."

Alonso also told THR, that the "Avengers" sequel would likely involve working with seven to 12 VFX vendors in five to seven different countries. Alonso noted during her keynote that working in multiple countries can benefit that process, as those in other countries 'sometimes have ideas that we don't have. That's what we gain by being global.'" At the same token, she said, "Hurts me that families are displaced.'"

On a lighter note, fans will be thrilled to see Robert Downey Jr., Chris Evans, and Chris Hemsworth in the next "Avengers" film, but they may be in for a surprise when a rumored new cast is announced in the future.

The highly anticipated "Avengers: Age of Ultron" is scheduled to hit theaters on May 1, 2015.
