AVENGERS: AGE OF ULTRONLast night's "Marvel Studios: Assembling a Universe" documentary brought, as promised, a first look at "Avengers: Age of Ultron" in the form of concept art. Perhaps most exciting, it's the first look fans have seen thus far of Quicksilver and the Scarlet Witch.

Mark Ruffalo spoke with Vulture about his upcoming "Avengers: Age of Ultron" reprisal of the Hulk, and as it turns out, his work has already begun.

"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," Ruffalo told Vulture. "So they're doing all the [background] plates for that now in South Africa, and then I start work in mid-April."

GHOSTBUSTERS 3Deadline spoke with Ivan Reitman, originally planned to direct "Ghostbusters 3," about the decision to step down from the director's chair and produce the movie instead.

"It's a version of 'Ghostbusters' that has the originals in a very minor role," Reitman said of the script by Etan Cohen. "When I came back from Harold [Ramis'] funeral, it was really moving and it made me think about a lot of things. I'd just finished directing Draft Day, which I'm really happy with and proud of. Working on a film that is smaller and more dramatic was so much fun and satisfying. I just finally met with [Sony's] Amy [Pascal] and Doug Belgrad when I got back. I said I'd been thinking about it for weeks, that I'd rather just produce this 'Ghostbusters.' I told them I thought I could help but let's find a really good director and make it with him. So that's what we've agreed will happen. I didn't want all kinds of speculation about what happened with me, that is the real story."

Reitman further hypothesized that production on the film would "get started by the fall, set in New York, but given the logistics and the stuff that happens, the beginning of 2015 sounds more likely."

X-MEN: DAYS OF FUTURE PASTFile this one squarely in the rumor column, but it's likely going to gain some steam in the next few news cycles. Show Biz Spy has an unconfirmed report that Kelsey Grammer has a cameo in "X-Men: Days of Future Past" reprising his role as Beast. According to Show Biz Spy, Grammer's cameo occurs "toward the end of the film" where he plays "an alternate adult Beast." If true, Beast would be the only X-Man other than Professor Xavier and Magneto to have both an older and younger version in the film.

That said, the "alternate adult Beast" combined with the title of the next film in the franchise -- "X-Men: Apocalypse" could mean that Grammer has been recast as Dark Beast, an alternate evil version of Hank McCoy that showed up in Marvel's "Age of Apocalypse" comics.

Either way, this is definitely only a rumor right now, and should be taken as such. Don't bet the farm on this one, though it would certainly be interesting to see Grammer in "Days of Future Past."

CAPTAIN AMERICA: THE WINTER SOLDIERCBR spoke with Joe and Anthony Russo following the premiere of "Captain America: The Winter Soldier," and the duo discussed a myriad of topics, including their involvement with sitcom writing and the connection to Captain America.

"It came naturally only because I've had an emotional connection to the character since I was 10," Joe Russo said. "When I was a kid, I did have problems with the jingoistic, sort of simplistic code of the character, and I would always imagine Steve McQueen in my head, just to give him that balance of bite and edge. I think that [Ed] Brubaker and [Mark] Millar have done a really interesting job in the last 10 years of finding that sweet spot for the character, where he has a level of machismo and a level of grit to him -- he is a soldier, after all -- without taking him away from his code. The goody two-shoes component is very dangerous, because the character can feel very preachy.

"It was a narrow target to hit, but it was one that's been in our brains for a long time, just from a taste standpoint -- how we prefer to see the character executed."
