Interestingly, rather then have the posters trickle out from Marvel HQ, the new bits of wall dressing were revealed by the cast members themselves. Robert Downey Jr. got a tidal wave of likes when he revealed the Iron-flavoured page on Facebook (with his added hint at a special announcement on the way), whilst Mark Ruffalo tweeted in the other guy as well. Taking this pattern into consideration, it might be worth keeping an eye on the social networking updates of Chris Evans, Jeremy Renner and Samuel L. Jackson. Ill bet my Marvel printed man pants that theyll be showing their one-sheets to the world over time as well. As an extra special observation and passing thought, you might recall that when the promo wagon for Avengers first rolled out back in 2012, Hulk was the last one to be revealed. Could this mean that something, or someone Marvel have kept hidden may be on the way for a full and official appearance? Keep your screens on and your Vision clear and be prepared for a few more surprises before Avengers: Age of Ultron arrives in cinemas April 24 in the UK and US cinemas May 1.
