 Up to this series, the pilot of each Star Trek series after the  first included a cameo of a character from the previous one.  However, because "Enterprise" takes place 100 years before the  original Star Trek, the cameo was not of a series character, but of  Zefram Cochrane (James Cromwell ), who appeared in  _Star Trek: First Contact (1996)_ (qv) and in the original series  episode #2.9 "Metamorphosis" portrayed by Glenn Corbett (qv).
