Mark Ruffalo has described The Avengers: Age of Ultron as 'cooler' and darker' than Avengers Assemble.
Ruffalo is set to reprise the role of the Hulk when filming on Age of Ultron gets underway later this year.
The Avengers: Age of Ultron is already one of the most anticipated films of 2015, and Ruffalo drops hints as what we can expect.
Speaking to MTV, the actor said: "I would say that it’s better, it’s cooler, it’s more awesomer.
"It’s a little bit darker, but also really has Joss Whedon’s incredibly, witty and sly sense of humour."
Ruffalo will reunite with Robert Downey Jr, Chris Evens, Chris Hemsworth, Jeremy Renner & Scarlett Johansson as they reprise their roles of Iron Man, Captain America, Thor, HawkEye and Black Widow.
But before we see Ruffalo return as Bruce Banner, he has also completed work on Can A Song Save Your Life? And Foxcatcher.
The Avenger: Age of Ultron is released 1st May 2015.
