In an interview with The Wall Street journal, Samuel L. Jackson gave some insight into all things Nick Fury after his super secret cameo at the end of episode 2 of Agents of S.H.I.E.L.D. Playing Fury, it seems, is old hat to Jackson; about the cameo, Jackson said, "I'm still playing the same guy, it's the same process. I just show up and they turn the cameras on and we do it." The scene played well and added some humor and connectivity to the larger universe without overshadowing the agents or the focus of the episode. Fury is, after all, the head cheese of S.H.I.E.L.D (for now) so it's not out of order to bring him into the show on occasion, despite some of the dissenting views about his appearance.
More interestingly, Jackson commented on the beginning of filing for Avengers: Age of Ultron and an addition to the cast. "I don't think we begin shooting before March of next year. I know we're shooting in London, that James Spader is Ultron and going to be the bad guy, and that we added Ms. [Elizabeth] Olsen, but I don't know what she's doing, if she's on the inside or the outside. I haven't seen a script."
While we've heard Elizabeth Olsen's name surrounding the role for some time now this is the first time anyone has come close to any sort of actual confirmation about Olsen taking on the role of Wanda Maximoff/Scarlet Witch. It seems that, despite the lack of an official announcement by Marvel, we will see Olsen and Aaron Taylor-Johnson as twin mutant Avengers Wanda and Pietro Maximoff/Scarlet Witch and Quicksilver. Very solid additions to an already outstanding cast.
