Henry Czerny on Edison Twins
I just watched and epsiode, One Way Ticket, where Henry played one of 2 bad guys counterfeiting concert tickets. He wasn't listed in the credits here on IMDB so I edited the page. Hopefully they update the cast listing for the episode.
Here is a screen shot of the cast from the actual episode credits:
