In Doctor Who episode #158 “The End of the World” the Doctor (Christopher Eccleston) takes Rose Tyler (Billie Piper) 5 Billion years into the future. In a scene where Rose talks to Cassandra (Zoë Wanamaker) in a room where historical items are on display, you can clearly see a copy of Harry Potter and the Philosophers Stone in a glass case.
