Chris Pine insists he is not feeling the pressure of taking on the role of Jack Ryan.
The 30-year-old actor is playing the CIA agent hero of Tom Clancy's spy thriller novels, who has already been portrayed on screen in several films, in new movie Moscow.
Chris - who has already tackled one established character playing Captain James Tiberius Kirk in J.J. Abrams' Star Trek movie - told Australia's Herald-Sun Newspaper: "Look, at the end of the day, people will obviously prefer one version over the other, whether it be Alec Baldwin or Harrison Ford or Ben Affleck.
"I feel the same way about Star Trek - the only thing I can do is the best version of myself. I can only bring who I am to bear on the part and people either like that or not."
Jack Ryan was the hero of The Hunt for Red October, Patriot Games, Clear and Present Danger, and The Sum of All Fears.
Chris admitted he hasn't read the completed script for Moscow yet, which is being directed by Lost's Jack Bender, and he doesn't know how physically demanding the role will be.
But he is not letting himself worry how audiences will react to his interpretation of the character.
He said: "Again, I don't have much control over that, so all I can ask of myself is to do my best, try my hardest and to make sure that we have a really good story to tell, and then give it to the hands of fate."
