We were all expecting a SuperMan cameo in Martin Campbell directed Green Lantern. This was not mere expectations as industry insiders had spread the news of SuperMan making an appearance in Green Lantern but now that seems to be all rumors. In a recent interview to MTV, Martin clarified that there are no such plans and he even went on to say that no other DC characters would be seen in the film. This automatically puts to end all speculations that was doing round for the past 1 year. Green Lantern is going single and that is quite some news!
