Los Angeles, Jan 31 (IANS): Actor-filmmaker Ben Affleck has decided to step down as director of "The Batman" but he will continue to produce the film as well as star in it.

"There are certain characters who hold a special place in the hearts of millions. Performing this role demands focus, passion and the very best performance I can give. It has become clear that I cannot do both jobs to the level they require," variety.com quotes Affleck as saying.

"Together with the studio, I have decided to find a partner in a director who will collaborate with me on this massive film. I am still in this, and we are making it, but we are currently looking for a director. I remain extremely committed to this project, and look forward to bringing this to life for fans around the world."

According to sources, the decision was solely made based on what's best for the project and had nothing to do with the disappointment of Affleck's recent direction job "Live by Night".

Affleck and Warner Bros will now begin searching for a new director. Sources say there is a shortlist and that "War for the Planet of the Apes" helmer Matt Reeves is among those on the list.

"Warner Bros. fully supports Ben Affleck's decision and remains committed to working with him to bring a standalone Batman picture to life," the studio said a statement.

Affleck has completed work as the superhero in "Justice League". He was preparing to go into preparation on the solo "Batman" movie this summer. Affleck co-wrote the script with Geoff Johns.

He first appeared as the superhero in last year's "Batman v Superman: Dawn of Justice".
