OMG its michael scofield from prison break!! The guy in trailer must be his doppelganger or twin. I'm seriosly surprised it is not wentworth himself. Looking back on the topics, I'm surprised no one mentioned it.
Uh, the guy in the trailer *is* Wentworth Miller. He starred in the original Dinotopia miniseries when it aired on ABC (the 4 hour tv special). He did not appear in the miniseries, so the trailer with him as well as the flashbacks from the miniseries showing him, are just being recycled from here. Most of the characters in the tv series following the original show are all recast. (And while they are ok, the original cast was much stronger IMO)
