Emma Watson has sent a note to Steve Carell after the Foxcatcher star opted to wear cufflinks that support Watson's #HeForShe gender equality campaign.

The handwritten note, that Watson photographed and shared on Twitter, reads, "Dear Steve Carell, You were pure genius in Little Miss Sunshine (one of my all time favourite films), my brother became obsessed with you after Anchorman. I wanted to marry you or have you adopt me after Crazy Stupid Love, I hated that guy you played in The Way Way Back, and then you were mindblowing in Foxcatcher and I think you're so awesome and now you are wearing #HeForShe cufflinks at the Oscars to support gender equality. Couldn't be more proud. Thank you. Love, Emma x"

Carell responded to Watson on Twitter saying, "Thanks @EmWatson. An honor to support #HeForShe and gender equality."
