Whilst a huge section of the X-Men fan base are petitioning for James Marsden to don the Cyclops shades once more, there are also strong calls for Jean Grey to reappear in the franchise. She was such a huge part of it in the early days, after all, and given that Bryan Singer's back on board, there are some that argue he'd at least give her a short cameo n the movie. Of course, Grey died in X-Men: The Last Stand. But given the power of time-travel in this movie, and the power of Grey's alter-ego, the Phoenix, surely anything is possible in Days of Future Past? Why It Could Be True: Famke Janssen, the actress who played Grey in the first three films, is listed as having a stunt double for the film on IMDB. She didn't exactly deny the rumours, stating "One never knows" when asked if a return was possible, and though this film's pretty packed out already, a surprise cameo, like with Cyclops, would be a hugely fan-pleasing moment. There will be surprise cameos in store, surely... but who will they be?
