1. An actor or actress that has NEVER been in Star Trek. Not even one-time guest stars (Famke Janssen), bit parts (Paul McGillion) or cameos (Christian Slater).
2. Whatever he or she is doing in a movie makes you think that they would be good in Star Trek in a similar role. So it's not enough that you want an actor in Star Trek; your avatar must be of a role that makes you think that.
3. Sci fi and fantasy roles are acceptable in this contest, so "Firefly" away if you must.
4. You may enter up to two avatars.
So for example, here's my first entry:
Russell Crowe as Captain Jack Aubrey in Master & Commander made me think he would be good as a Starfleet captain.
