The future of 'The Batman' has been up in the air for months but it looks like things are moving in the right direction as it's set to go into production next summer.

The future of the blockbuster has been up in the air since Ben Affleck - who has played the Caped Crusader since 2016 - stepped down as writer and director, but it looks like things are still moving in the right direction as Warner Bros. have reportedly approved new director Matt Reeves' script and scheduled a start date.

The Wrap's Umberto Gonzalez tweeted: "LIL BATMAN UPDATE: The studio loves Matt Reeves' first draft of his BATMAN script, he is currently doing revisions & the film is being eyed for a hopeful summer 2019 production start. 

"Of note, the current DC regime is committed to getting this take on the Caped Crusader correct! (sic)"

Despite things progressing quickly, producers are yet to find someone to play the fictional superhero as it's been claimed that Affleck may not reclaim his black cape and bat mask.

However, Jon Hamm - who is a "huge comic book" fan - recently admitted that he would be keen to follow in the 46-year-old actor's footsteps - providing the script is strong. 

He said recently: "It depends on the script, what the story is.

"I am a huge comic book fan, always have been. I've read comic books since I was nine or younger. And I'm pretty knowledgeable about a lot of them. And I like the genre, and I like when they're done well."

But the 47-year-old star has stressed that he hasn't had any official conversations about the possibility of taking on the iconic role.

He said: "I have had rumours about that since probably season one of 'Mad Men'.

"I have never had a conversation with anybody about it, literally. And I've sat in the room with all these guys. I have never been offered anything. I think the internet wants what it wants. But, I mean, a lot of people have to sign off on that, obviously not just the internet."
