This is Mark Hamill, aka Luke Skywalker from the Star Wars franchise.

This is Sebastian Stan, aka Bucky Barnes from the Captain America franchise.

And, apparently, the two have a long-standing joke that they are low-key father and son. Why? Because the resemblance is truly ~freakish~.

Like, they're BOTH fully in on it and it's genuinely one of the best things happening in nerd world RN.
@HamillHimself we know, Sebastian told us already! 😜❤️
He even kind of sounds like a young Hamill??? What is this magic???
To further the gag, Hamill tweeted out another side-by-side comparison this past weekend.
Sorry to disappoint you but I refuse to say "Sebastian Stan-I AM YOUR FATHER!" (even though, in fact, I am) 😜… https://t.co/msqhEAYmvB
And fans rightfully lost their goddamn minds.
every time mark hamill tweets about sebastian stan i gain +90000 life points
mark hamill and his son sebastian stan
"Mark Hamill about his "son" Sebastian Stan" is always my favourite headline to read
Some are even DEMANDING a father-and-son film, which I would promptly give all of my money to forever.
Can @HamillHimself, Seb Stan and @PeterWIKraus act in a movie as father and sons please? cuz I would honestly sell my soul to see dat happen
i really need a father-son movie between mark hamill and sebastian stan please
Even Hamill wants in on this, THE MOVIE GODS HAVE SPOKEN.
@TaanujaR @PeterWIKraus How about a Science Fiction Adventure with a twist? I travel back in time & Sebastian plays… https://t.co/CkqRaq9nQs
So, in short, I will not rest until I see this happen.
wait... mark hamill is sebastian stan's dad? the winter soldier's arm suddenly makes way more sense.
