As comic book readers know, Ultron is an indestructible, artificially intelligent robot that decides to take down the human race starting with the Avengers.
Marvel’s ‘The Avengers' flick was a box office blast: From left, Scarlett Johansson, Chris Hemsworth, Chris Evans, Jeremy Renner, Robert Downey Jr. (Iron Man), Mark Ruffalo (Hulk).
Given the importance of the robotic super hero Vision to the original Ultron storyline, the signs point squarely to Vin Diesel's role in the movie, as one of several new super heroes ready for their big screen debuts.
It's also possible that original Avenger Ant-Man, aka Ultron's creator Dr. Henry Pym, will join the team. The character is already the subject of a standalone film to be written and directed by Edgar Wright.
