Michael Fassbender has said he thinks he knows where the Assassin's Creed big-screen adaptation went wrong, admitting that the film "took itself too seriously".

The 40-year-old Irish-German actor starred in the leading role and was a producer on the movie adaptation of the hugely-popular video game series. However, the film disappointed in the box office in 2016, pulling in $240 million worldwide on a reported budget of $125 million.

Michael Fassbender says he would make Assassin's Creed "more entertaining"

Fassbender has now said he would have made the movie more entertaining and said the lukewarm reception the film received "wasn't ideal".

In an interview with website Movie 'N' Co for his upcoming film The Snowman, he said of a potential sequel: "I think we missed an opportunity there a little bit. So we'll wait and see what Ubisoft are coming up with. But right now, I don't know."

When asked what he would have done to make the movie better, Fassbender replied: "I would make it more entertaining, that's really the main note.

"The feeling of the film, I think it took itself too seriously and I would get to the action a lot quicker. I think there's three beginnings of the film, which is a mistake.''

Fassbender's latest film The Snowman, which is based on the best-selling crime novel by Norwegian author Jo Nesbø, sees the actor take on the lead role of detective Harry Hole, who is on the hunt for a serial killer. It hits cinemas in Ireland this Friday, October 13.
