The 44-year-old actor is in the process of creating a new standalone movie focused on the famous DC Comics character which he is writing, directing and starring in.

Affleck has the working title 'The Batman' - which will see Joe Manganiello play supervillain Deathstroke - in place for his film but he thinks he might change it.

He said: "The movie I think is going to be called 'The Batman'. At least that's what we're going with now. I might change it.

"We're working on the script. The script is going well. I'm really excited about it."

Affleck first portrayed Bruce Wayne and his superhero alter ego in 'Batman v Superman: Dawn of Justice' and although the blockbuster received many negative review it proved to be a huge financial hit banking $873.3 million worldwide.

The Oscar winner is incredibly be proud of the film - directed by Zack Snyder and inspired by Frank Miller's dark graphic novel 'The Dark Knight Returns' - because it is the biggest hit of his stellar career so far.

In an interview with Fox 5 DC, he said: "It was a huge hit movie - more people went to see that than any movie I've ever made in my career. You know, it's the biggest hit of my career. And then it had a lot of editorial negativity. The fans went, and it got a lot of positive response. It was interesting, that movie, because it was judged not necessarily on execution so much as [on] its tone. People seemed to want to have a lighter tone to the movie ... Tone isn't a qualitative thing - it's subjective, right? Some tones resonate with me that might not with you ... I loved it."

Affleck will next be seen in Batman's cape and cowl in superhero ensemble movie 'Justice League', with filming wrapping on the project in London at the weekend.
