Film wise I'd love to meet any of the main cast of Rogue One or Fantastic Beasts, a bit unrealistic as that may be.
Emilia Clarke and Sam Clafin (me before you) would make me super happy too!
TV shows I'd love anyone from the casts of the walking dead, stranger things, buffy the vampire slayer, scream queens, MTV's scream, shadow hunters, pretty little liars, gossip girl, desperate housewives, the vampire diaries & gilmore girls!
