Kit Harington has joked about reuniting with his Game Of Thrones co-star Richard Madden in superhero film Eternals, saying it was written into his contract that they would have limited screen time together.

The pair played on-screen brothers in the long-running fantasy series, but only appeared in the first two episodes of the first series together, before Jon Snow (Harington) and Robb Stark (Madden) had to go their separate ways.
