Leave it to the Vision to be omniscient.

According to Paul Bettany, “Avengers: Age of Ultron” is the grandest film in the Marvel universe.

“This is the biggest thing Marvel have ever done,” he told the Radio Times. “It was enormous. I remember we were at Comic-Con and they showed a portion of the footage, and I was just gobsmacked. And I looked down the row and every one of the Avengers was the same, including Samuel Jackson. And his whole modus operandi is ‘I’ve seen everything before, I’m the most chilled out, relaxed man and I’ve seen everything,’ and he was as knocked out as anyone. It’s huge.”

The film will reportedly set a new VFX shot count record for a Marvel film.

Bettany, who will play the red-faced android hero the Vision in “The Avengers” sequel, also described “Age of Ultron’s” set as the largest he’s ever stepped foot on.

“One (part) seemed to be the corner of a town, with helicopter cameras and drone cameras flying about,” he said. “I just haven’t seen anything that big, so it was like being a kid on a film set again.”

Bettany previously voiced Jarvis, Robert Downey Jr.’s virtual assistant, in “The Avengers” and all three “Iron Man” films.

Directed by Joss Whedon, “Avengers: Age of Ultron” also stars Downey, Chris Hemsworth, Chris Evans, Mark Ruffalo and Scarlett Johansson. It hits theaters on May 1.
