Which actor played Rollin Hand in the original TV series?

Martin Landau played Rollin Hand in the original *Mission: Impossible* television series.

Rollin was the Impossible Missions Force's master of disguise, actor, magician, escape artist, and impersonator. The character was often described as “the man of a million faces,” making Landau's ability to portray multiple identities central to the show's elaborate deceptions.

Landau appeared during the series' first three seasons, from 1966 to 1969. He was initially billed as a special guest star in season one because of contractual and film-career considerations, then became a regular cast member in the second season. His then-wife, Barbara Bain, played fellow IMF agent Cinnamon Carter.

Viewers sometimes confuse Landau with Leonard Nimoy, who joined the series later as another disguise specialist, Paris. Peter Lupus played the strongman Willy Armitage, while Sam Elliott appeared much later as Dr. Doug Robert. Thus, among the listed choices, Landau is the single canonical answer for Rollin Hand.
