Bryan Singer tweeted the following set image from X-Men: Days of Future Past where not only do we see Hugh Jackman and Nicholas Hoult in the background, but reading the license plate could hint at the mutant, Longshot.
Longshot, while technically not a mutant, is known for his "luck powers," and was actually created in an alternate dimesion known as the Mojoverse.
It's unknown if the car pictured is actually a prop in the movie or belongs to someone on set for the film.
The movie does feature a large number of characters from the X-Men universe, so maybe Longshot will get the luck of the draw as well.
X-Men: Days of Future Past has a May 23, 2014 release date starring Jennifer Lawrence, James McAvoy, Michael Fassbender, Nicholas Hoult, Anna Paquin, Ellen Page, ShawnAshmore, with Hugh Jackman reprising as Wolverine, and returning cast members Patrick Stewart and Ian McKellan.
