I always said stewart should have played both Shinzon and Picard. But that would have required a bit of difficulty to pull off. And they could fake them being in the same scene using computer editing and cgi. Or do the splitscreen thing they did on back to the future II i think that was the movie.
The whole thing with b4 did not work. And ripping off spocks death in star trek II and redoing it with data was just stupid.
The sequel would have been the search for data instead of the search for spock,lol.
Actually i find the young picard angle interesting and i wonder if they ever considered doing a prequel to star trek the next generation with Picard as Captain of the USS Stargazer. We know they decided like Harve Bennet to do the academy days of Kirk story. Well in JJ's movie they just graduate at the end of the film to the crew of the enterprise.
The young picard who fights the nausicans in a bar fight and gets stabbed through the heart is a lot like the rebel that Chris Pine plays in this film. That picard was a lot like kirk in his younger days. The Captain Picard of the Enterprise D was a thinker and diplomat before a man of action. Though they ignored this in the films like First Contact where he was made an action hero,lol,.
