Two television specials featuring the character followed, both occurring and released in 1994, two years after the series ended. In the first one (MacGyver: Lost Treasure of Atlantis), MacGyver teams up with his former college archaeology instructor, Professor Atticus (Brian Blessed), to help him prove his theories about ancient Atlantis while dodging the bullets of genocidal Yugoslav troops, a Greek revolutionary and a ruthless treasure hunter. Soon thereafter (MacGyver: Trail to Doomsday), he investigates the murder of a friend in Britain, and eventually traces it to an unscrupulous businessman who sells nuclear arms research for profit. No mention in either special is made of Pete Thornton, Jack Dalton, MacGyver's son Sean or any of the show's other regulars.
