'Avengers' actors like each other too much, says Joss Whedon

Joss Whedon has said that the cast of The Avengers get along too well.

The director revealed that he was hoping the actors might experience some real-life tension that would help drive the on-screen conflict.

"I was like, well, if they hate each other, I guess we can use that," Whedon told Entertainment Weekly. "But they don't."

The Buffy the Vampire Slayer creator went on to reveal that the cast and crew of the movie spend much of their time on the Albuquerque set going to dance clubs.

Whedon went on to admit that he is re-writing portions of the ensemble film as he shoots it.

"There is a weird element of - they handed me one of the biggest movies of all time, and I'm making it up as I go," Whedon confessed.

Avengers star Chris Evans recently revealed that Whedon chose his look for the ensemble film, saying that the director had a certain vision for Evans's Captain America.

Evans previously described the movie as well-balanced, claiming that Whedon has brought "substance" to the Marvel Studios film.

The Avengers opens in theatres on May 4, 2012.
