recent interview. Hypable made a post about this rumour which can be seen here.
More interestingly, a few supposed stills from the Catching Fire trailer were posted on Twitter and Tumblr, among much speculation and excitement. They look very convincing, but sadly were first posted on the night of April 1st, as an April Fools' joke. A comparison below shows that this "still" was photoshopped from the interview scene in The Hunger Games.
Fingers crossed we may see a little "sneak-peek" in the coming weeks!
