Challenge of the SuperFriends

In the last scene when Batman gives his speech, Black Vulcan is seen with no collar to his costume. But in the final shot, a collar is covering his entire neck.

Superman said they'd taken care of the whole Legion of Doom, but had only actually defeated Grodd and Black Manta. There were still eleven villains that could have kept going.

When Superman, Grundy and Bizarro are all in one shot near the end, it looks like they're in a jungle, but they were in the lab.

Wonder Woman claims she can tell which Cheetah is the real one because the holograms of her don't cast shadows. Neither does the one Wonder Woman lassoes, however.
