Ever since he joined Twitter in April 2014, Robert Downey jr has been really embracing social media. And the direct line to the star has been unsurprisingly embraced by his massive fanbase, making his own Twitter feed a source of instant breaking news and viral content.
The way news actually breaks now on Twitter is a topic for another day but right now RDj is sitting on something big. He tweeted this yesterday.
So he doesn't want to spoil our Tuesday but something huge is clearly on the way. The biggest thing he's involved with is definitely Avengers: Age of Ultron right now and with that release coming in early summer 2015 now would be a perfect time to get the promo train rolling with a proper trailer.
We also know that footage from the film has already been shown to select audiences and, as comicbook.com points out, he's certainly drawing attention to his t-shirt which looks very much like the Black Sabbath shirt he wore in The Avengers.
Keep a close eye on RDj's Twitter today for this annoucement!
Avengers: Age of Ultron is coming to cinemas on the 1st of May 2015.
