In a Variety article talking about The CW (the combination of The WB and UPN launching this fall), it is mentioned that the “Aquaman” series, titled Mercy Reef, may be promoted on Superman Returns in theaters:
It’s expected that much of the CW’s promo resources will be aimed at letting people know there’s a new network in town — with shows they already know and love. Parent companies Time Warner and CBS Corp. will help with everything from saturation spots on CBS Radio stations to a potential “Aquaman” trailer attached to summer tentpole “Superman Returns.”
We’ll keep you updated on this.
