Abrams appears to be moving quickly from Plan A - Benicio Del Toro, who bowed out when he wasn't offered enough quatloos for the role made famous in the original TV series and "Star Trek II: The Wrath of Khan" by Ricardo Montalban.
Ramirez is not well-known to American audiences, obviously. But that shouldn't make any difference, since it would be his performance that is most important. And he does have a role in next year's "Wrath of the Titans," and that's kind of close to "Wrath of Khan," right?
Plan C, according to Variety, would be another unknown in Jordi Molla.
Abrams needs to cast his Khan Noonien Singh soon because production begins next month.
We're not totally sold on the recycling of a Classic Trek villain for the new movie. Then again, no one asked us.
