The CW has recently unleashed the teaser trailer for the tenth and final season of Smallville, which is set to premier on Friday September 24th at 8/7c. The footage doesn't really show much, which is why it's called a teaser. We saw a lot more great looking footage at Comic-Con. Hopefully a non bootleg version of that footage will be released soon. Check out the teaser trailer and let us know what you think!
