With the trailer for [The Avengers: Age Of Ultron](tag:293035) released and the film itself, a what looks like a certain Police Box makes a cameo appearance in the trailer. Fans of Doctor Who will be very familiar on who's it is. If you skip all the way to 1 minute and 33 seconds and pause the video. In the background what looks like the TARDIS is there. Could this really be the Doctor? If it is really him, where is he and what's he doing there? It would even be better if the Doctor himself makes a cameo appearance in the background somewhere.
Pause it at 1:33!
