Canon Cast

So for the canon cast in all Star Trek series, I retain all original actors.

Enterprise

The Internet Movie Database shows the main canon cast and much of the supporting canon cast. Most bit players’ names are from Memory Alpha.

Main Canon Characters

Jonathan Archer, Travis Mayweather, Doctor Phlox, Malcolm Reed, Hoshi Sato, T’Pol  and also Charles “Tripp” Tucker III. The name is ‘Trip’ in canon, but I had an old friend who was a III, and he spelled it ‘Tripp’. Consider it homage to a guy I was friends with throughout his life.

Supporting Canon Characters

Admiral Black (Gregory Itzin); Elizabeth Cutler; Daniels (no first name in canon; I have named him Richard); Gral (Lee Arenberg); Colonel Phillip Green; and also Major Jay Hayes (no first name in canon, so the actor speculated that the name was Jay or Jeremiah).

Also, Erika Hernandez; Jim Horan (“Future Guy”, no name in canon) (James Horan); Derek Kelby (no first name in canon) (Derek Magyar); Neil Kemper (just a first initial in canon) (Nathan Anderson); Kolos (JG Hertzler); Mestral (J. Paul Boehmer); Susie Money (just a first initial in canon) (Dorenda Moore); Michael Rostov (Joseph Will); Thy’lek Shran (Jeffrey Combs); Soval (Gary Graham); Stron (Michael Krawic); and also T’Pau (Kara Zediker).

O’Laskey).
