In one of the more bemusing rumours to surface recently, attendees of Czech SFF convention Tricon have reported that Steven Erikson, author of the Malazan Book of the Fallen, will be appearing in the Game of Thrones TV series as an extra. According to the reports, Erikson will be playing a horse-rider and will briefly appear in the background of a scene, possibly waving. The reports seem unclear on whether Erikson was directly invited to appear by Martin (who befriended Erikson at the World Fantasy Convention a few years back) or if Erikson auditioned on a whim due to his horse-riding skills.
Still trying to get official confirmation on this, but intriguing news if true.
In other Game of Thrones-related news, filming on the series, now a month old, proceeds apace. The Hand's Tourney was filmed last week and scenes set in Winterfell will begin filming next week. This week saw a number of scenes at the Crossroads Inn being filmed as well, including some scenes set in the book elsewhere (the sequences set at Castle Darry in the book appear to have been relocated to the Inn for cost reasons).
Update: Apparently Erikson was unable to take part in the project after it initially appeared to be on the cards, which is a great shame. Of course, there's always next year. Maybe we could get a rotation of UK-based epic fantasy authors appearing in cameo roles in the series? Joe Abercrombie as a wizened old warlock in the House of the Undying in Season 2, anyone?
