Rick Marshall

Rick Marshall was one of the main characters featured in the 1974-1977 children's television series Land of the Lost. Played by actor Spencer Milligan, the character was introduced in the series' pilot episode "Cha-Ka" and appeared in thirty out of forty-three episodes in total. Spencer Milligan departed from the show in 1975 and his character was replaced with Rick Marshall's brother Jack played by Ron Harper. The character was re-imagined for the 2009 comedy feature film version of Land of the Lost where he was played by Will Ferrell. Ferrell's depiction of the character was radically different from the one portrayed by Spencer Milligan.
