Star-Lord in "Guardians of the Galaxy" has more in common with Han Solo than being a wisecracking space criminal with more charm than sense: The actors playing them were both 35 at the time of their big breakthrough.
That's also the same age several other stars were in some of their biggest sci-fi films, including Arnold Schwarzenegger, Kurt Russell, Jeff Bridges and Keanu Reeves.
Of course, it doesn't apply to everyone: Christopher Reeve was 25 when "Superman" came out in 1978 and Chris Evans ("Captain America") and Chris Hemsorth ("Thor") won't turn 35 until 2016 and 2018, respectively. But you have to admit, it is a pretty cosmic coincidence.
Harrison Ford in 'Star Wars'
In "Star Wars," Harrison Ford played the roguish smuggler who gets caught up in the rebellion against the evil Empire: He eventually gets the girl and shows he's not just out for himself -- and inspired legions of smart-mouthed imitators in the process.
Arnold Schwarzenegger in 'Conan the Barbarian'
The former bodybuilding champion had his first starring role as the musclebound hero in this 1982 action flick. He was, you guessed, it, 35 at the time.
Jeff Bridges in 'Starman'
When he was 35, Bridges starred as an alien who takes on the form of a widow (Karen Allen)'s dead husband in 1984's "Starman." He received his third Oscar nomination for the role.
Kurt Russell in 'Big Trouble in Little China'
Russell was also 35 when he starred as Jack Burton in this ridiculously fun B-movie with John Carpenter in 1986. Sure, he's probably better known as his other Carpenter character, Snake Plissken in 1981's "Escape From New York," but he was in fine form as the heroic, John Wayne-loving Burton.
Keanu Reeves in 'The Matrix'
Reeves was already known for action films like "Speed" and "Point Break," but he didn't play his signature role -- Neo in "The Matrix" -- until 1999, when he was 35.
Chris Pratt in 'Guardians of the Galaxy'
Chris Pratt is Peter Quill (aka "Star-Lord") a wise-cracking space criminal who inadvertently ends up becoming a hero who saves the galaxy. Sound familiar?
Sigourney Weaver in 'Aliens'
Weaver had already played Ellen Ripley in 1979's "Alien," but it was with its sequel, 1986's "Aliens," that she really hit the big time: She landed on the cover of Time magazine and received her first Academy Award nomination. She was 35 when "Aliens" began filming.
