There’s been a lot of talk lately about all the mutant cameos appearing in the X-Men spin-off X-Men Origins: Wolverine, but we haven’t heard much about any characters set to show up in the other spin-off, X-Men Origins: Magneto. Until now. According to George “El Guapo” Roush at The Latino Review, the Magneto film will feature either Beast or Nightcrawler. The uncertainty over which lies in the fact that, while on a visit to a creature effects shop, Roush saw a photo (or rendering) of a blue-costumed character who he was told is a young Beast (played by Kelsey Grammar in X-Men: The Last Stand). Yet the character is described by Roush as having a tail, which suggests that the effects person was mistaken and that it’s really a young Nightcrawler (played by Alan Cumming in X2: X-Men United). Roush has printed an update acknowledging the Nightcrawler possibility but doesn’t understand why the effects guy would have had it wrong.
