As J.J. Abrams' Star Trek 2 speeds towards its January 15th start date, casting continues to heat up.  Last month, we learned Benicio Del Toro would be playing the villain (who may or may not be Khan); last week we heard Alice Eve (She's Out of My League) had signed on to play a new character to the franchise; and now Variety reports that Peter Weller, the original RoboCop, is joining the party.  There are currently no details on what role Weller will play, and given Abrams' penchant for secrecy, we shouldn't expect to hear those details any time soon.This won't be Weller's first time with the Trek franchise.  He previously played the character "John Frederick Paxton" in two episodes of the TV series Star Trek: Enterprise.  Let the rampant speculation begin that he's playing the same character in Abrams' film (even though the character was killed on Enterprise).  Star Trek 2 opens May 17, 2013.
