Movies
Book of movie
Radio drama (book of movie and radio drama might be swapped)
Novels, comics, etc all fall under here.
So basically, if it takes place in a movie, it overrides everything.
If I'm not mistaken, the Infinities line is an alternate "What if?" series. I know that they also changed the comics within the last year or so to include a logo that says "this stuff may or may not be canon". The comics use to actually write stories that would fit in canon. Now, I don't think they even bother.
