His character also appeared as a rehabilitation therapist in the Delerue Center for Rehabilitation where Locke was given rehab in "Cabin Fever", though he was only barely visible in a few shots (and not at all in the standard definition broadcast). (His character was not Locke's physical therapist, but rather, a different therapist seen in the background.)
According to his blog, Denny and his wife Jana moved to Honolulu in August 2007, having spent their lives prior to that living in the Midwest. By chance, Denny met Benjamin Linus portrayer Michael Emerson at the post office on Friday, November 16, 2007.  On Thursday, March 6, 2008, Denny applied to be an extra with the Lost casting office, and was offered a role as a physical therapist extra in "Cabin Fever" on March 31, 2008, a role which he filmed on April 3, 2008. Denny returned to the Lost set for an additional extra role on September 12, 2008.
