Old_Zircon - 2011-06-21 Classic, I still have this on VHS.
Caminante Nocturno - 2011-06-22 I saw this on the Scifi Channel back when it was still called that and they showed scifi movies.
dododge - 2011-06-26 I saw this during the theatrical run, probably on opening night. I can't remember if it was still called "Killbots" at that point or if the title had already changed between the trailer and the local release. I do have a vague recollection that I might have been the only one in the theater.
