Production began last month on Avengers: Age of Ultron, with a video from the South African set revealing destruction from a Hulk rampage. Mark Ruffalo himself wasn't present for this Johannesburg shoot, but he explains why in a new interview with Vulture, where he also teases a possible romance for Bruce Banner, while commenting on how Scarlett Johansson's pregnancy will alter the production.

Back in January, Latino Review's El Mayimbe revealed that the Hulk is "actively dating" in this Marvel Phase Two sequel, although that report has not been confirmed as of yet. When asked about the possibility of a Hulk romance, Mark Ruffalo had this to say.

"That may or may not be true."

The only confirmed female cast members for Avengers: Age of Ultron thus far are Scarlett Johansson as Black Widow, Cobie Smulders as Agent Maria Hill and Elizabeth Olsen as Scarlett Witch. Do you think Bruce Banner is dating any of these women? Of course, it's possible that more female cast members will be confirmed as we get closer to production starting up next month. El Mayimbe has teased that Captain Marvel is accounted for in the script, but there has been no conformation or word of that from anyone else.

Speaking of the production, Mark Ruffalo reveals that he has already shot motion-capture footage of Hulk on a sound stage. The work being done in South Africa will serve as the background plates for these scenes, while he starts the bulk of his shooting in mid-April. Here's what he had to say, when asked if he was on the set in South Africa.

"The Twitter-verse is all alive with that [question]! I actually already shot a lot of that stuff, we did it on motion capture, so we did a lot of that on a stage. So they're doing all the [background] plates for that now in South Africa, and then I start work in mid-April."

When asked about Scarlett Johansson's pregnancy, the actor revealed they plan on shooting more closeup shots of the actress.

"They're going to shoot a lot of closeups [of her]."

When Marvel's The Avengers was released in 2012, many fans enjoyed the rivalry between Bruce Banner and Robert Downey Jr.'s Tony Stark/Iron Man. The actor has just read the script for Avengers: Age of Ultron, and revealed that he hopes fans will get to see more of this dynamic in the sequel.

"I'm guessing you will."
