Whedon: I could kill off Avenger
Joss Whedon has teased that he would get rid of one of the Avengers superheroes - but only if there's a good reason.
The filmmaker, who will be directing the Avengers sequel, Age Of Ultron, admitted he is "always joking" about killing off one of the lead characters.
"Um maybe? But I'd have to have a really good reason, a really great sequence for (Marvel bosses) to go, 'We'll cut off a potential franchise, that's fine!'," he told Entertainment Weekly.
"They know, as any good studio does, that without some stakes, some real danger, how involved can we get? We don't just rule it out across the board, but neither is the mission statement 'Who can we kill?'"
He added: "We try to build the story organically and go, 'How hard can we make it on these people?'"
Non-Avenger SHIELD agent Coulson (Clark Gregg) met his deadly fate in Avengers Assemble, although he is returning for the TV series Agents Of SHIELD.
Joss also confirmed that Ultron would be the only villain in the sequel, and that there will be no appearance from Thor's evil brother Loki, played by Tom Hiddleston.
"Every movie is going to be a different villain. Loki's awesome and he is awesome in Thor 2. But The Avengers is a different thing," he said.
"I worked with Tom more than any other actor (in the last film) because he was the only villain and there were six heroes. And he was as great as anyone I've ever worked with, and I got why people loved the character. But it's an Avengers movie."
Robert Downey Jr, Mark Ruffalo, Scarlett Johansson, Chris Hemsworth, Jeremy Renner, Samuel L Jackson and Chris Evans are set to reprise their superhero roles in the follow-up.
