It's been 10 years since Chris Evans, Michael Chiklis, Jessica Alba , and Ioan Gruffudd starred in Fantastic Four, and the new reboot is in theaters this week. Kate Mara, Jamie Bell, Miles Teller, and Michael B. Jordan are playing the titular Marvel superheroes, who are pitted against megavillain Victor Von Doom. Before the movie is released, let's take a look at how the new kids stack up against the original cast!
Reed Richards/Mister Fantastic
Then: Ioan Gruffudd
Now: Miles Teller
Age: Gruffudd originated the part of Dr. Reed Richards when he was 31. At age 28, Teller is a little younger.
Pedigree: Gruffudd had a number of roles before he starred in Fantastic Four, but none supernotable. Miles Teller has been all over the genres, appearing in Footloose, 21 & Over, The Spectacular Now, That Awkward Moment, Divergent, and Whiplash. It's safe to say he can tackle action, too.
Sue Storm/Invisible Girl
Then: Jessica Alba 
Now: Kate Mara
Age: Alba was just 24 when she played Sue Storm, while Mara is 32.
Pedigree: At the time she signed on for the first movie, Alba had appeared in a number of high-profile projects, including Honey and Sin City. Mara starred on TV hits like House of Cards  and American Horror Story, and she's also been on the big screen in 127 Hours and Transcendence.
Ben Grimm/The Thing
Then: Michael Chiklis
Now: Jamie Bell
Age: At 42, Chiklis was substantially older at the time he played Ben Grimm than 29-year-old Bell.
Pedigree: Chiklis was (and still is) best known for The Shield, while Bell's been in the spotlight since his breakout role in 2000's Billy Elliot. He's been in a number of drama and action films since then, including the highly controversial Nymphomaniac.
Johnny Storm/The Human Torch
Then: Chris Evans
Now: Michael B. Jordan
Age: Evans played Johnny Storm when he was 24, and Jordan isn't far off at 28 years old.
Pedigree: Evans had costarred in a few movies like Not Another Teen Movie and The Perfect Score before taking the role of Johnny. Meanwhile, Jordan starred alongside Teller in That Awkward Moment and earned critical praise for his role in 2013's Fruitvale Station. On top of that, he's got major TV cred for roles in Friday Night Lights and Parenthood.
