The latest big-name star to make the trip to the Calgary Comic & Entertainment Expo? Nathan Fillion.



The current star of ABC crime dramedy Castle, Fillion is revered in geek circles for playing Capt. Malcolm Reynolds in the Joss Whedon space western Firefly, and its big-screen adaptation Serenity.



Fillion, who hails from Edmonton, joins a growing list of big-name stars at the Expo, including Peter Dinklage, Gillian Anderson, Michael Biehn and John Carpenter, among others.



The Expo takes place April 26 to 28 at the BMO Centre.
