10. Jensen Ackles
Jensen Ackles has played Dean Winchester on Supernatural for 14 seasons, and seeing as the series will end... eventually, it's likely he is on the lookout for a new role. Even if he sticks with the show for years more, that doesn't necessarily mean he can't become the next Wolverine, and it's something fans have been talking about online.
He's expressed a full range of emotion playing Dean throughout the years and has proven time and time again that he's a phenomenal actor. Fans of Supernatural, as well as Wolverine, have expressed an interest in seeing him play the part.
Ackles' career has predominantly been in the realm of television, though he has appeared in several movies. He voiced Jason Todd/Red Hood in Batman: Under the Red Hood and played Jason Teague on Smallville, so he's no stranger to the world of comics book acting... rumor has it he once auditioned to play the Dark Knight.
After playing two DC characters, it may be time for Ackles to pick up one of Marvel's most famous. While he is talked about online as a potential actor for the part, he may prove too old for Marvel/Disney to go his way. He turns 42 in March 2019, which may make him too old for the studio to cast him.
