Why He Should: Former Pixar man Brad Bird has achieved so much in the course of his relatively short career. Ever since he made his feature film debut with The Iron Giant, Bird has been pulling out the stops at each and every turn: he's never made a bad movie. And that ultimately comes down to the fact that Bird is a perfectionist, presumably a trait he perfected over at Pixar. An expert on all things pop culture and an action-orientated director who doesn't shy away emotional themes, Bird would be completely in his element for Star Trek 3. Like J.J. Abrams before him, Bird made his live-action debut with a Mission: Impossible movie, and arguably crafted the best and most exciting entry yet. He also showcased a visual style than runs close to Abrams' own. Bird's proven himself, then, as a director capable of making the fourth installment in a long-running franchise the best one yet. Certainly he could do the same for Star Trek's third entry. Why He Shouldn't: It would be nice for Bird to move away from existing properties and onto some original projects. He's also arguably be a better choice to helm a Star Wars movie than a Star Trek one, given the more fantastical aspects of his movies thus far. Overall Probability: 5/10
