Once Hollywood discovers that two stars have good onscreen chemistry, they don’t let it go. (See Katharine Hepburn and Spencer Tracy or Fred Astaire and Ginger Rogers, for example.) Sometimes, though, these actors are not actual couples in real life, they just look really, really good together, and Hollywood has no shame in replicating a film’s on-screen romance to cast the couple opposite one another again in a completely unrelated film. As Oscar favorites Eddie Redmayne and Felicity Jones gear up to play an onscreen couple again in Amazon Studios’ The Aeronauts, take a look back at some other Hollywood favorites–from Emma Stone and Ryan Gosling to Julia Roberts and Richard Gere–who tend to repeatedly play romantic leads opposite one another. Just remember: they’re not real-life couples, they just play them on screen—again and again (and sometimes again).
