A member of SHH appears to have gotten his hand on an official cast list for Avengers: Age Of Ultron. If you'd like to know if Thanos will appear or find out who Julie Delpy ("Before Midnight") or Linda Cardellini ("New Girl") are playing in the film then proceed. If not, then run away as fast as you can.
If you were hoping to see The Mad Titan in Avengers 2, well you are in luck, because he's in it! According to this cast member list Josh Brolin, who voiced Thanos and provided a motion-capture performance in Guardians of the Galaxy, will make an appearance in Age Of Ultron.
Who is Cardellini playing? Based on this list, she's Laura Barton. She's the wife of Hawkeye/Clint Barton in the Ultimate universe of Marvel Comics. Furthermore, Ben Sakamoto and Imogen Poynton will play Cooper and Lila Barton. Poynton is the young actress that portrayed Rhomann Dey's (John C. Reilly) Krylorian/Xandarian hybrid daughter in James Gunn's Guardians of the Galaxy. Could Hawkeye have a wife and kids in the MCU that we didn't know about?
Who is Delpy playing? The character's name is Madame B. and that doesn't ring any bells for me.
For Black Widow, we saw that she has a flashback to when she was learning ballet. It seems that Doctor Who actor Julian Bleach will play her Ballet instructor.
