Avengers: Age of Ultron is currently shooting in Johannesburg, which looks to be the real-world setting for one of the film's action sequences (though rumors about Black Panther's fictional home turf Wakanda persist), as the first set photos/videos reveal.
The popular theory so far is that the truck explosion and chaos shown below (filmed by onlookers and posted to their Instagram account) might have something to do with a rampaging Hulk, even though a previous report claimed that Hulk actor Mark Ruffalo isn't present. Could Bruce Banner's green-skinned side (or, as he calls it, the "other guy") still be the source of trouble shown here?
These videos (check out another HERE) may well tease a Hulk attack sequence, which raises even more questions about the character's role in the Age of Ultron story. In the past, there's been talk about another Hulk solo movie being released as part of "Phase 3" (or maybe 4), while the old rumor was that the Avengers sequel will conclude with Banner's expulsion from Earth's Mightiest Heroes - due to him being unable to properly control his Hulk side. That could pave the way for a film inspired by the "Planet Hulk" and/or "World War Hulk" comic storylines - though, Whedon has dismissed the Planet Hulk idea as "nonsense."
On that note, you can head over to Comic Book Movie for a look at images snapped up from the Avengers 2's South Africa shoot (offering a more up-close-and-personal look at the flaming vehicle depicted in the video above).
Still, even if the sequence being shot here has nothing to do with Banner or the "other guy," there's a cloud of uncertainty surrounding the Hulk's role in this story (to mention nothing of his future in Marvel Movies). There's littler reason to doubt that Whedon's "dark" and "cerebral" script for Age of Ultron will touch on the duality of Banner/Hulk, while the actor who plays them has some ideas about a possible future movie - none of which suggests that the rage-fueled superhero will be, say, just carrying out missions for S.H.I.E.L.D. with nary a problem in this film.
Of course, there's also the chance that the South Africa segment has something to do with Jeremy Renner as Hawkeye (the actor metup with Whedon recently ) - in which case, you have to wonder what "covert" mission he's on that involves causing so much (and such public) collateral damage...
