Michael Fassbender says his film adaptation of popular video game Assassin's Creed is still going ahead and the that the script if currently being developed.

Speaking to gamer website IGN, the Irish-German actor said: "Nothing has changed. I'm still a part of Assassin's Creed, and we're working on the script as we speak. Actually, I'm going to go back and see the writers when I get back to Europe."

Fassbender is producing the film, due in August 2015, himself and Justin Kurzel, who recently finished directing Fassbender in Macbeth, is also thought to be involved. 

Fassbender also told IGN that he plans to create a balance of new and original material from the video game.

"You know, we absolutely want to respect the game," he said. "There's so much cool stuff in the game, that we're actually spoiled for choice in terms of what we can use and what we can't, but we also want to bring new elements to it and perhaps our own version of things that already exist in the game."

"But we're definitely making a feature film, and we're approaching it as a feature film, as opposed to approaching it as a video game.

"So I'm really excited about it, and we're working very hard to make sure that we've got the best and most exciting, original package."
