Sylvester Stallone just can’t stop killing bad guys, and in addition to the upcoming Rambo V: Last Blood, it looks like he’ll also be doing just that in MGM’s Samaritan.

Reported by Deadline, MGM has snatched up the original spec script, described as a dark superhero movie, from writer Bragi F. Schut and Stallone’s Balboa Productions.

Stallone is currently attached to star.

Deadline notes, “Plot details are scarce but the pic has been described as a dark, fresh take on the superhero genre.”

Writer Schut recently penned this year’s Escape Room.
