Its really awful for the actor I think.
Nimoy was always Spock as well as Luke always was Luke.
There are some roles actors choose to play which grant them enormous respect and attention for the moment but destroy their carrer as they everybody remembers them as in their first role.
Example ? Okay Orlando (I am gay Lord no. 1) Bloom played an absolute sissy in Troy but whas also killing with a bow.
So if you watch the movie he is also shooting like a sissy and weird looking due to seperate him from good ol´ Legolas doing his shooting.
Its really hard for them I think. And I think it will be boring for the actors to shoot the 1 Billionst episode of a series.
Really funny about Star Trek: New actor is introduced and will die in the same episode. Mostly in a heartbeat after introduction.
So guy, you will be introduced and then you will fall to the ground and die. Thanks Mr. Producer I really feel why I´ve been for 12 years on schools to learn how to act and sing. Shame man.
Everybody should post best scene with scotty and best scene or episode/movie ever out of Star Trek !
