From here there has been quite a few appearances I'd missed, http://www.imdb.com/name/nm0001795/
-All his movies up to Walking Across Egypt and maybe before Monday I'll get to see Speedway Junkie.
(I know I may not get to see the TV appearances that noted from the site)
-I cannot forget Jonathan being Randy on Home Improvement though
-Appearance he guest star in Smallville one time (smiles)
