Interesting premise, but stories tend to be repetitive...
“Man From Atlantis: The Complete Television Series” stars Patrick Duffy as a man who may be the last survivor of the lost continent of Atlantis. Dr. Elizabeth Merrill (Belinda Montgomery), a scientist working with the Navy, is called in to examine a mystery man who was found in the ocean. This man, who they name “Mark Harris,”  possesses webbed hands and feet and gill tissue which let him survive underwater indefinitely, and give him strength, speed, and stamina when submerged. Mark must remain in constant contact with water or weaken and eventually die. In other words, air is his Kryptonite. Mark has no memory of his life before being discovered, but decides to work with the Navy helping them with underwater research and rescue operations and confronting bad guys, such as the mysterious Mr. Schubert (Victor Buono), who tries to use the ocean’s resources to take over the world.<br /><br />This show was produced during an era in which NBC was in ratings limbo. None of its shows clicked and the network began to take chances on anything that it thought would have a shot at success. Patrick Duffy was a charismatic lead, and the show treated the character’s unusual powers seriously, unlike the cartoonish “Batman” of a few seasons earlier. The show had an interesting premise and a solid pilot but, largely because of a restrictive budget, tended to resort to tired stories with less-than-eye-popping special effects. Victor Buono was fun as the nutty Mr. Schubert, who turned up in several episodes, serving more as comic figure than serious threat to Mark. Other guest stars included Kareem Abdul-Jabbar, Pernell Roberts, Rene Auberjonois, and Pat Morita.<br /><br />Four made-for-TV movies about this character were shown during the 1976-1977 season, garnering very good ratings, which prompted NBC to put the show on its schedule for 1977-1978. It premiered on September 22, 197, but the rigors of producing weekly episodes became too daunting a task, and the series was canceled. It’s last telecast was July 25, 1978.<br /><br />There are no bonus features on the 13-episode 4-disc DVD release.
