Falling Skies (2011) - Official Trailer. Not sure how this series completely slipped under my radar but now I know of itI am searching it out much like the aliens search out the children. What looks like an Alien version of the Walking Dead comes with the backing of Dreamworks and Steven Speilberg so expect strong characterisation and higher than normal production value than the average Sci Fi channel original.

Total Recall 2012 Official Trailer [HD]: I am a big fan of the Arnie total recall, and was sceptical of a remake (or more accurately a re-intepretation of the source material) but after having seen the trailer I am now expecting big things, perhaps even bigger then the Schwarzenegger classic.
