Geeks of all kinds are converging on the Metro Toronto Convention for Comicon.

One of the highlights comes Saturday night with a reunion of the cast of Star Trek: The Next Generation. Stars including Patrick Stewart, LeVar Burton & Marina Sirtis will share behind-the-scenes stories from the TV show. Fans have to buy tickets on top of their Comicon admission to get in.

Actor Sean Astin, featured in The Hobbit, Lord of the Rings & Goonies, is also a guest.
