Joseph Gordon-Levitt gets a point for DARK KNIGHT RISES, plus LOOPER for time-machine stuff and INCEPTION for mind-control stuff and GI JOE for nanobots.
RH also gets credit for youtubing with the fans about it, and being genuinely weird in a cool way.
By the OP’s original limitations, Ladyhawke, Buffy, Sin City and Batman wouldn’t count, sorry.
Christopher Lee isn’t the King of science fiction, though. He’s more like Pope.
I thought he played E.T., wearing a rubber suit.
Speaking of rubber suits, how about Janos Prohaska? Star Trek, Escape from the Planet of the Apes, Voyage to the Bottom of the Sea, Lost in Space, The Outer Limits…
Oh. “Current actor.” Never mind; he daid.
I know that Yoda makes an appearance in ET, but I never noticed R2D2.
Even with the OP’s limitation, can we count League Of Extraordinary Gentlemen to track Sean Connery back through The Avengers and Highlander and Time Bandits and Meteor and Zardoz to his legend-making turn as James Bond back when that meant rocketing around with a jetpack and fighting dudes with bionic hands and talking his way out of death by frickin’ laser?
I know. I was pushing it a bit.
Y’know, even if we for some reason disallow Laurence Fishburne threatening the Fantastic Four and handling that story about those Kryptonians and narrating the adventures of the Teenage Mutant Ninja Turtles, he’s still out there battling Predators and leading a post-apocalyptic Colony and investigating an Event Horizon and patiently explaining that . . . well, unfortunately, no one can be told what the Matrix is; you have to see it for yourself.
Felicia Day and Chris Hardwick.
In fairness, I’m not sure it’s possible to craft a definition for science fiction that includes Star Wars but excludes The Avengers.
