If you haven't been keeping up on the new iteration of Battlestar Galactica now would be a GREAT time to rent/buy a season or two.  This show ROCKS THE HOUSE and it's not just a &quot;boy boy sci fi toy,&quot; either.  I've got the gals at work hooked on it!

Also, I second the vote for Dune as posted above.

And keep in mind that sometime when you're not on the plane you should rent Lust in the Dust.  Have a few drinks along with it.
