His body became completely paralyzed after falling off a horse in 1995, but he remained on the set until his scenes were completed.
In the season 2 DVD extras, the producers mention that they wanted to get Reeve into Smallville for a long time and wanted a perfect character for him; they think his portrayal of Virgil Swann makes for a great "passing the torch" moment.
