Los Angeles: `Avengers` made history by becoming the third biggest film of all time but its director Joss Whedon believes it could have been better.
The director hopes to improve as he brings Marvel Comics` greatest superhero team together in the sequel, reported Entertainment Weekly.
"When I think of a great film, I think of something that`s either structured so perfectly like The Matrix or made so lovingly like The Godfather Part II. There was haphazardness in the way it comes together ? not just the people, but the scenes. I don`t think you`d look at it and go, `This is a model of perfect structure.` You`d go, `This is working.`," Whedon said.
`Avengers` made USD 1.5 billion at the box office besides getting critical approval and Whedon is happy to have pulled of a great hit.
"I like it. I`m proud of it and I like its imperfections. The thing I cared most about?making a summer movie like the ones from my childhood?is the thing that I pulled off," he said.
The film stars Chris Evans, Chris Hemsworth, Cobie Smulders, Gwyneth Paltrow, Jeremy Renner, Mark Ruffalo, Robert Downey Jr, Samuel L Jackson, Scarlett Johansson.
In `Avengers` sequel `Age of Ultron`, superheroes Iron Man, Thor, Captain America and The Hulk will take on the titular robotic villain. The writer-director said he already knew how to make the film a better movie.
"I want to be clearer about how I engage the audience, and where
I take them. I want more control visually, more time to prep it. Not that I didn`t dictate every shot ? I did. But there`s only so much you can do when you`re making a summer film when the ball is already rolling as fast as it was when I got in. Why do it again if you can`t do it better?"
`The Avengers: Age of Ultron` is due out in 2015.
