Sci-fi highs

A star-spotting meet for autograph hunters, film fans and Trekkies, this two-day show has guest appearances by Batman old and new (Val Kilmer and Adam West), and The Lord Of The Rings stars Andy Serkis (Gollum) and Billy Boyd (Pippin). Star Trek: The Next Generation crew members include Levar Burton and Brent Spiner, but if your taste runs to home-grown sci- fi, you can worship at the feet of Tom Baker instead. Special 'cast reunions' and screenings take place for Blake's 7( Sat) and Red Dwarf(Sun) and there are evening talks from The Lord Of The Rings' cast and crew. You'll also find 750 dealers selling posters, photos and other memorabilia.
