The Marvel Cinematic Universe has yet to make an attempt to tackle this once dominant movie genre, but I think a fun to at least pay homage to it would be by casting the actor as Carter Slade, better known as the Phantom Rider.
Kevin Costner is much better known for westerns like Silverado and Open Range, which is how he earned the lead role in the Yellowstone cast as John Dutton.
Maybe, whenever the MCU decides to reboot the property, that could be a fun way to bring Phantom Rider into franchise, as played by Kevin Costner.
Before you get this mysterious, 19th-Century hero confused with a certain skeletal cyclist from Marvel, I will have you know that Ghost Rider was actually the original moniker of Carter Slade after the slain former school teacher was resurrected by a Native American.
