I've seen reported on a couple of websites that there is a new trailer/commercial posted over at Google Video for an Aquaman TV series. Before you get all excited let me point out that this video has been out for about 10 months and is the promo trailer for the Aquaman pilot that was supposed to air on the CW network but was never picked up (which I first reported on back in November 2005).
You can see the video for yourself here.
If you watch the video, notice that Justin Hartley is playing the title role. After the failed pilot he went on to play Green Arrow in Smallville instead.
Oh, and if that's not enough, you can check out AquamanTV.com for verification. :-)
