Jon Hamm Out To Betray Ben Affleck Over ‘Batman’

Jon Hamm of "Mad Men" fame has his sights on stealing bloated buddy Ben Affleck’s Batmobile to become the Dark Knight!

“Jon’s gunning hard for the role,” a source spilled to The National ENQUIRER! Although the two have been pals since co-starring in Ben’s 2010 film “The Town,” and boozed together before Jon got sober in 2015, the coveted character may be up for grabs — and Jon is no Joker about wanting in!

“They enjoyed working together and have been on good terms ever since,” the source said. “But Jon knows Ben has faced some criticism over ‘Batman v Superman’ and ‘Justice League,’ and frankly thinks he’d be better suited for the job. This is business for Jon — not personal.”

While Ben is still the one answering the Bat-Signal, things are likely to change. “Of course, Ben’s not officially out of the role yet,” said the source, “but the writing’s on the wall, and Jon’s desperate for the gig — friend or not.”

Since Ben’s split from Jennifer Garner, his struggles with substance abuse have been making headlines and he hasn’t committed to future Batman projects. Jon is ready to fly in and has been “carefully courting” director Matt Reeves for months.

“Matt thinks Jon is charming and was a big fan of ‘Mad Men,’ so it seems like a great transition to him,” the source snitched. “Jake Gyllenhaal has also been chasing the role. But Jon is closer to Ben’s age and look, and will be a smoother replacement to fit into the plans already in place.”

While Ben’s career stalled with ongoing rehab trips this year, Jon’s star rose with his recent work in the film “Baby Driver.”

“Things have been going great for Jon since ‘Mad Men’ wrapped,” according to our insider. “An iconic part like this would take his career to the next level. He doesn’t care whose toes he has to tread on to get there.
