Rupert Grint pays tribute to “Harry Potter” dance partner Maggie Smith: 'Always hilarious and always kind'
For his post, Grint used a still from their most memorable scene together in Harry Potter and the Goblet of Fire, in which McGonagall teaches Gryffindor students how to dance by forcing Ron to reluctantly partner with her during a demonstration. (It's a tough job, but someone had to prepare those nerds for the Yule Ball.)
