I just watched Jonathan Ross (BBC interview show) and this time Bob Hoskins and JK Rowling were two of his guests. During his interview with Bob Hoskins, Jonathan mentioned it was weird Bob had never starred in any of the Harry Potter films. Bob then told about a previous encounter with JK Rowling, where she had promised to write a character for him. Cut to: JK Rowling who kind of cringed, clearly having forgotten that she had ever promised that. She did, however, say that there will be a new character in book 7: a older male wizard, which could be played by Bob Hoskins. This could be only useless interview prattle, but it might turn out to be an actual casting.

Update: I sent this same bit of info to AICN and they’ve actually posted it!
