Chemistry is a strange thing to nail in Hollywood. How do you put two people together and hope there will be sizzling romantic sparks? Now, there’s a wave of actors who are pulling double duty in the chemistry department. On-screen pairs like Godzilla‘s Aaron Taylor-Johnson and Elizabeth Olsen and The Fault In Our StarsAnsel Elgort and Shailene Woodley aren’t just selling the sex, but they’re selling the idea that they’re siblings in their other big onscreen roles.

Aaron Taylor-Johnson and Elizabeth Olsen are about to fight Godzilla as man and wife on the big screen, but they’ll both be crossing over into the A-list when they play Marvel’s most famous super siblings, Quicksilver and the Scarlet Witch, in next year’s Avengers sequel. Meanwhile, Shailene Woodley and Ansel Elgort might be due to make us cry our hearts out when they star in the adaptation of The Fault in Our Stars, but they’ve already played the Prior siblings in Divergent this year.

These two couplings aren’t the only duos pulling double duty in Hollywood. Here are 10 famous film and television couples who have fallen in love and kept things all in the family. (And yes, we’re counting former Get Real siblings Anne Hathaway and Jesse Eisenberg‘s pairing in Rio as a romantic hook up.)
